Title: Add a tip for Photoshop please!
Post by: Stef. on December 17, 2007, 10:09:26 AM
I thought I start a new thread for digital darkroom tips. Hope this is a good idea and the listmom does not tell me off?
I am regularly asked for faster ways of doing things or "secret" tips. So forgive me if some of the stuff might be "cold" coffee but perhaps it is helpful?

Now this is a way of converting a colour picture to black and white without the channel mixer and the need to add anything up to 100%: I assume most of it works in Elements the same way or similar?

(1) open up your colour image in Photoshop
(2) create an adjustment layer: (this is at the bottom of the layer's palette- the grey and white circle. Choose "hue saturation"- change nothing just click O.K.
(3) create another adjustment layer- again hue saturation. This time drage the saturation slider all the way back to
-100
(4) Go back to the first hue saturation layer- click on the circle opening it up once again and play with the lightness slider. Now the neat thing is that under "edit" you can choose the separate colour channels and change the lightness of each individually without the stupid percentage of the channel mixer!

Hope this helps the one or other of you?
Happy photoshopping!

Great idea Stef.

ok, here's another tip.

If you are zoomed in, working on a small area of the image and don't want to keep zooming in and out to see if it's looking right, just open a new window of the same image.

Go to Window > Arrange > New window for ....

A new instance of your image will open up. You can have one zoomed out and work on the zoomed in version. The other image will update when you make changes.

This depends on whether you have enough screen space to open two images of course :)

not really a tip, more an alternative sharpening tool.

Add duplicate layer, filter, high pass filter. Select soft light blend. Adjust opacity to between 60 and 80%. Flatten.

No unsightly haloes!

My tip of the day:

An alternative sharpening method - arguably the best there is:
(1) Image -> Mode -> Lab Colour
(2) Click in the layer palette "channels" and select the "Lightness" channel
(3) click select -> all -> edit -> copy
(4) in channels palette click little arrow on right hand side "new channel" -> just click O.K. then -> edit ->paste -> rename channel "sharp" by double clicking on Alpha
(5) keep that channel selected -> filter -> stylize -> find edges
(6) image -> adjustment -> levels: adjust so that you get a nice strong contrast (left arrow: pull it towards the middle)
(7) stay on that channel -> filter -> blur ->gaussian blur: radius around 1 pixel
(8) still on same channel go back into image -> adjustments -> levels: fine tweak the contrast once more
(9) in channel list select the lightness channel
(10) go to select -> load selection -> "sharp" with invert ticked
(11) now: filter -> unsharp mask -> around 300 % radius 1 threshold 4
(12) go back into your channel palette and delete channel "sharp"
(13) click RGB in channel pallet
(14) click select -> deselect
(15) convert back to RGB: image ->mode -> RGB

This is considered as one of the best methods to sharpen an image. Now it seems to be very long but you can make an action out of it! Not sure how this works in Elements but I  have been told that most of these things work in Elements as well. So sorry for my biased tips- but I work with Photoshop.

Have fun!

creating your own borders

(1) Open your image
(2) Create a new layer
(3) Edit -> Fill -> Foreground Colour (set to white)
(4) In the Layers Palette: Set Layer from "Normal" to "Lighten" and start painting with black onto this layer. Where ever you paint the original image comes through.

Keep in mind the following:
(a) taking grey instead of black let's the image only partially shine through
(b) take "artistic" brushes to make a black line/border all around the inside of your image- then take the magic wand tool to selct all the remaining white within the black line and fill it with black- voila you have an artistic border
(c) keep in mind to play around with the tool presets to change the brushes to for instance chalk.
Have fun

How to add snow to your images using elements

Open up image>Layer>new layer (rename snow) click ok
Switch foreground background colour  to black foreground
press alt del keys (layer turns black)
Filter>texture>grain>grain type>enlarged>intensity 100-contrast 0  > ok
Enhance>adjust colour>remove colour
Filter>blur>gaussion blur> set to 1.9 > ok
Enhance>adjust lightness>bright/contrast> contrast 95 < brightness -1 >ok
Windows>layers>snow layer>blend mode> change from normal to screen
Image>transform>free transform w=300 h=300>click crop
Select eraser tool>opacity 50% brush size 800 remove some snow, by clicking the snow will darken in places giving a more natural appearence.

Thats it, The more you play around with the eraser the better it can look. You can also add another sow layer with bigger or smaller flakes over the top of this one by selecting a bigger or smaller width and height size in free transform.

This is a very quick attemp, will post a better one later

O.K. my tip of the day: history brush

Now this is a tool that unfortunately is highly undervalued by most photoshoppers and therefore I thought I make you aware of some of it's possibilities:

Now the cool thing about the history brush is that you can make any changes to an image than take a "snapshot"- go one step back in the history palette- in other words "undo" what you have just done and then use the history brush by clicking next to the snapshot and apply "partially" what you have just undone.

Example: you decided that part of you image needs more contrast but not all of it.
(1) apply levels/ curves to the whole image paying particularly attention to the part of the image that you would like to have more contrast and ignoring the rest of the image.
(2) take a snapshot of the adjusted image
(3) go one step back in your history palette- in other words undo your level/ curve adjustment
(4) choose the history brush > tick next to your snapshot > start painting over the part of theimage that you really want to adjust

TIP: don't forget you can change the opacity of your brush and therefore the strength of the adjustment.

This is a fantastic way to partially adjust contrast and also to change the amount of contrast in one go. Alternatively you would have to choose different parts of the image and make different adjustment layers.

Also the history brush lets you not only change the contrast just imagine what else you can do with that! You can for instance tint the whole image in any colour and then undo it and apply it partially!

Just give it a try it is really worth it!
Happy photoshopping!

Fast way for removing sensor dust in Camera Raw

(1) Use the spot removal tool in Camera Raw (= retouch tool) on a single image
(2) Use the synchronize button (displayed at the top left when multiple files are selected)
(3) tick the spot removal button on the top right hand side once the synchronize window opens and the sensor dust on all the selcted images should be removed

Keeping the Raw files until the very last minute

Now this is a very handy one- one that I did not know until lately...

We all prbably agree that it is the raw file is the "best" quality available with most of the information contained within the image? Any kind of conversion be it Tiff or Jpeg is less quality than the original raw file and yes I do know about losless conversion...so here is a simple trick to keep the original raw file even in CS!

Once you have done you conversion in RAW converter instead of just clicking "open" hold down the shift key while clicking. This places you raw file as a smart object layer into a new document in PS. Now you can continue editing using a standard non-destructive workflow such as adjustment layers etc. At any time you can re-open you raw file in ACR by double clicking the layer.

Neat one isn't it?
Happy photoshopping

Edge Sharpening in ACR or Lightroom

Most people I meet don't know for what the "masking" slider is in the sharpening dialogue of ACR or Lightroom.
If you view your image at 100% you will recognise that by slowly moving the control to the right the sharpening effect is only applied to the edge detail.
This is very handy if you have a noisy image to start of with or if you don't want to sharpen things such as skin.

Gazraa if you are using CS3 it is really good at matching differing exposure levels when stitching - much better than CS2.

Correction of Colour Casts

Now the following are two methods to remove colour casts- which one works better depends often on the image and you should try both!

(1) open image > layer > new > layer > edit > fill > use 50% grey > OK > set layer blending mode to difference > layer > new adjustment layer >threshold > OK > drag slider all to the left- the image will become white > slowly drag the slider back to the right- the first areas that appear are the neutral midtones > hold the shift key and move your cursor exactly over that first point and click in the image > click cancel in the treshold dialogue box > drag your grey layer 1 in the layers palette to the rubbish bin- you don't need that one anymore as you have found the point in your image that "should" be neutral grey > open: levels or curves > chose the midtone eyedropper (the one under options in the middle) and click where you have left the colour sampler tool point in your image- this should remove all colour casts

Problem

Sometimes there is no neutral grey in your image- than do the following: (or you can try both versions and see what works better)

(2) open you image > layer > new adjustment layer > threshold > OK > move the slider all the the left and then slowly to the right > click with the shift key hold down on the first point that appears > now move the slider all to the right and slowly from that position back to the middle > when the first points appears > shift click again > once you have set both markers click "cancel" in the threshold dialogue box. You now have two markers in your original image that are the darkest and the lightest points in your image > open levels/ curves > chose the black point eyedropper and click in the darker marker and do the same with the white point eyedropper.

Both of the above methods work usually quite well in eliminating any colour casts- but not always as usual.

(3) one last thing to try: open your image > choose the eyedropper tool and click somewhere in your image where you know that point should be white. Then: > layer > new > layer > edit > fill >foreground colour > image >adjustments > invert > lower the opacity of this layer to somewhere around 10 - 20% and set the blending mode to either colour or hue

Hope this helps!

Remedy for shooting through glas also: a good way to improve midtone contrast

open image > copy the background layer > apply unsharp mask with the following settings: amount: 40%; radius 30 pixels; threshold 0

This should eliminate the haze created by shooting through glass and is generally a good way to improve midtone contrast. Play around with the settings a bit but keep the radius high. If it is too strong you can always lower the opacity of the duplicated background layer.

Stef.

Question:
why would you copy the background layer? is the original background still used at all or should there be a blending mode change in there too?...Gazraa

Answer:
You duplicate the background layer for a) the chance to play around with opacity- just in case the effect is too strong and b) you should never do anything on the original background- as it is destructive (call me nitpicking- but it's just that I always first duplicate the background.

No you don't change the blending mode- you can flatten it once you are happy.

colour correction- the right settings for levels and curves

Something that just crossed my mind: a lot of people seem to use not exactly the "best" settings when using the white/grey/ or black eyedropper tool in levels or curves. Here is what you should do:

open any image > open curves or levels (doesn't matter the settings will be automatically saved for both) > double click the black colour picker (this opens the settings dialogue box: enter the following values for the R, G, and B fields: 10 in each > O.K. > do the same with the white colour picker but now enter: 245 in all three fields > O.K. and finally do the same with the grey colour picker tool- this time entering 133 in all three fields (this sets the neutral grey) > O.K. > click once more O.K.- it will ask you whether you want to save these settings > yes

By using 10 for the dark colour picker we make sure that we get dark shadows while still maintaining some detail- the same for white and 133 is the neutral grey.

Try it- it makes you life easier... ;)

converting to black and white

well here is another way to convert an image quickly and effectively to black and white:

1. open image
2. go to image menu > mode > lab colour
3. click on the channel menu (next to layers) > click lightness > click back on layers
4. image > mode > greyscale > click O.K. when asked to discard layers
5. go to image > duplicate
6. set blending mode of the duplicated layer to multiply > lower opacity to somewhere around 10- 20 %

This is definitely a better way to convert an image to grayscale than just clicking grayscale as it preserves the highlight details in your image.
Just one way to do it...

Happy photoshopping!

CS3: Black and White converter

This is just a very short tip but extremely useful and many people don't know it:

Once you have opened the black and white converter in CS3 (I would suggest as an adjustment layer as this is non destructive) move your cursor outside the dialogue box into the image and hold it over the area you would like to adjust (darker or lighter). Now- here it comes: click-drag directly in your image. Moving the cursor to the left darkens that particular area and moving it to the right lightens it! No more guessing which of the many sliders you have to adjust to get that particular point in your image darker/lighter- your cursor knows which colours are below it and which colour combination and it will move all the sliders simultaneously that affect that particular point in your image! (You might want to have a look at your sliders and how the move because sometimes the effect is very subtle and you might want to strengthen it by directly moving the sliders once you have found out which ones they are!) ;)
Don't forget- if you like your combination you can save it under the presets.
Hope this helps?
Stef.

converting to black and white

We have done a couple of b/w conversions so far but this one is one of my favourite ones!

1. open you colour image
2. set your foreground colour to black by pressing D on your keyboard
3. layer > new adjustment layer > gradient map > now you have two options: either you just click O.K. and voila you are done or you might want to adjust the midtones/ contrast:
4. click once directly in the b/w gradient- this opens the gradient dialogue box: click under the gradient somewhere in the middle of the whole line > this will turn your image much darker BUT: double click the colour stop you have just put in the middle under your gradient and this will open another dialogue box > you will see in the big colour square on the left hand side bottom a little white circle > click on that circle and move it a bit up (straight line) > release the mouse from time to time to check your results > moving the circle up and down will adjust your midtones > click O.K. > O.K. again > O.K. again once you are happy. If you would like to colour your image at the same time just move you little circle a little bit to the right and see what happens.

Variation:
a) Last but not least you can lower the opacity of that gradient map layer and you will have a "slightly" coloured image.
b) Click on your original background layer> new > adjustment layer (this will create an adjustment layer between the gradient map layer and the background layer) > hue saturation > play around with the saturation slider until you are even happier!

This is a very easy and effective way to convert your images to black and white! Now you might wonder why we have now SO many different ways of converting colour to black and white? Guess it all boils down to taste. Sometimes when I am not completely happy with my conversion I duplicate the original image a couple of times and try all methods- even worse- if I am still not happy I might take two different conversions copy/ paste one of them into the other and start masking/ erasing part of one to let the other one "shine" through.

Some of you might have figured out by now- I just love b/w! :P

Hope this is useful for some of you and this is not only CS3!

Clippings Masks or How to put an image in your type/ t-shirt/ car design (works with all editions of Photoshop)

This is for type that you want to design yourself:

1. create a new document in RGB mode > press D to set foreground colour to black
2. choose your type tool > type whatever you want in big bold letters
3. open the image you want to put inside your type
4. press letter V (=move tool) > click inside the just opened image and drag it over onto your written text
(you have now three layers with the image on top)
5. you might want to resize the top layer: edit > transform > scale so that it fits better over your written text
6. once resized make sure the top layer is selected: press command+G/ alt+ctrl+G and your image will be inside your text! (You can reposition your image purely by dragging it over your written text)

Variation:
To make it look better apply a drop shadow: click the type layer > layer > layer style > drop shadow (or directly in the layers palette- it is the little f icon) > play around with angle/ distance/ spread and size
If you want to make it even better: go back into layer style and click bevel and emboss: play around with outer/ inner bevel...and size

A last remark: this technique works for all sorts of things: you want to put an image into a t-shirt? Easy- peesy: cut out the t-shirt > put it onto a new layer> open your "design" image > drag it over the t-shirt > resize it and clip it to the t-shirt by pressing alt+ctrl+G

From now on your can even design your own cars...
Hope this is at least fun- if not entirely useful and it is not black and white!

Quick fix for under/- overexposed images:

This can work wonders...

1. duplicate your background layer in Photoshop
2. underexposed images: set the blending mode of this duplicate layer to screen to lighten the image
    overexposed images: set the blending mode of the new layer to multiply to darken the image
3. if step 2 is not enough just repeat it and lower the opacity of that layer until it looks good.

Note: if you only want a partial effect either erase part of the layer or play around with layer masks!

Beauty tip: whiter teeth

select your teeth in PS (lasso works quite well but you can combine various methods by using shift/ alt etc to add/ subtract from you selection) > feather the selection by 1 pixel > create an adjustment layer "hue saturation" > choose the yellows from the drop down menu > drag the saturation slider pretty much all the way to the left > drag the lightness slider slowly to the right >click O.K. > play around with the opacity of that layer until you are happy.

You can save yourself the dentist that way ;)

Okay this was just playing.....Oldman River T.U. (Trout Unlimited) is a conservation group I belong to. So I typed the name and placed the body of a rainbow trout behind. (Yeah, the text is too dark in upper left. Just playin'.)

Questions. Is this what you were getting at? Did I miss something? (I use Elements 6, v CS3) Doing it your way, does colored text is stand alone? Versus showing up on a black background? I used layers "multiply" I think.

PS: I did a (maybe) cover shot last fall for the publisher of a magazine...HE wants to be on his own front cover. His teeth are a tad yellow..ecru. I lightened them more or less like you said. Looks great.

Yes- that looks brilliant! Well done. Basically in a nutshell: whenever you have any kind of selection- might be text, a shirt etc. and you put anything above that layer and group/ link it with the layer below than it will only show up within the selection. Now this can be actually really useful if you want to design something from scratch - let's say you want your own car design- select the outline of your car put your design on top of it and link those two layer and voila your design is just within the outline of your car. For text effects it is quite useful as well as you have shown!

Beauty tip eyes:

1.a. the most important tools in my opinion for enhancing the eyes (works also for the hair/ lips) are the dodging and burning tools: dodging: set range to highlights and exposure  to 5% and go over the white part of the eyes (you don't have to be too precise as it will only affect the highlights of the eyes- so you can go over the whole eye!)
burning: set the exposure to 5% and range to shadows and go once more over the eye- this time making the pupil/ iris of the eye darker
1.b. alternatively if you want to get the eye whiter:go to the layers panel and create a new adjustment layer "curves" > click O.K. without changing anything > set blending mode to screen (don't worry at this stage that the whole pic get lighter) > press ctrl - I > press the letter D > press the letter X > take the brush tool set to a small brush and start painting over the white bits of the eye (play around with brush size and opacity of the brush) > you can adjust the opacity of the layer as well. (I do prefer solution 1a though...)

2. If the eyes are slightly red- before you do step 1: select the whites (I prefer the Quickmask and brush tool- but any selection tool will do!) > select > modify > feather 1 or 2 pixels > image > adjustments > hue saturation > edit: red > drag the saturation slider to the left and the lightness slider a bit to the right and this should get rid of the red eyes

3. intensify the eye colour: Select the brown/ green/ blue part of the eye (iris) > modify > feather 1 or 2 pixels > ctrl + J (pastes the eyes onto a new layer- or you can go into layer > new > layer via copy) >set the blending mode of this layer to multiply and lower the opacity

4. Want to give the person a different eye colour? Select the braun/ green/ blue part of the eye (iris) > modify > feather 1 or 2 pixels > image > adjustments > hue saturation > tick the colorize box and play with the hue and saturation sliders

Keep in mind: 1.a. works wonders on hair and lips as well and is a very good alternative to sharpening the image at some times as it will raise the contrast! Give it a try and let me know what you think!

Happy photoshopping!

Clive and Rob- thanks for your kind words. Good to get some feedback. Clive with your teeth: you might want to consider to clone a bit around to get rid of the grey filling? Also: on a general note- be very careful how much you whiten the teeth- they still need to look realistic. For girls (sorry know that's sexist) I usually do a bit more than for boys...

Now here is another very neat trick that works wonders with skin marks or probably also in your case with the grey tooth: removing skin blemishes

take the colour picker and pick a colour close to your blemish > choose your brush tool and set the mode either to "lighten" (if it is a darker spot that you would like to get rid of) or to "darken" (if is is for instance a scar that is lighter than the rest of the skin) >play around with the brush opacity and start painting over your blemishes. Don't forget to sample "new" colour from time to time.

This is very effective for instance if you need to remove thread veins in faces or if your subject has dominant veins on his/her hand. The fact that you can alter the opacity of the brush is very useful in this case as this is difficult with the stamp tool. Also: sometimes you want to weaken wrinkles but not totally remove them (for that you would take the healing brush tool) and than this brush technique comes in handy.
(For instance with your tooth- you  might not want to conceal the fact completely that this guy has a filling but want to weaken the appearance subtly for this try the above)

As usual- happy photoshopping!
Stef. :P

HIi Stef
Great stuff again reckon you should write a book.Digital magic by stef.I like to use the paint brush tool soft brush and use the colour picker also like the healing tool very quick to use.

I have just used this in another thread but it fits better in this one:

Image effects: "Lith" here is how this goes:

start with a colour image in RGB mode > image > mode > lab colour > in channels palette next to the layer palette click the lightness channel > image > mode > grayscale > O.K. > image > mode > RGB (And no I am not making a mistake here ;) ) > layer > new adjustment layer > hue/saturation > tick colorize box and the following settings: hue 40; saturation 25; lightness 0 > layer > new adjustment layer > brightness/ contrast with the following settings: contrast -10 (careful it is minus!) > layer > new adjustment layer> curves: now here it gets tricky: go with your cursor along the line until you find point 65 > click on your line and put under "output" left to your curve: 2; now find point 114 > click and put under output 130 (the easiest way to do this is just to click somewhere above the last point on your curve and then move that point until you find 114) > find point 190: output 211 (Now you have a pretty wild curve! If you have problems with this last "curve" step you can leave it out) > set opacity of your curve layer to 50% and set the blending mode to "luminosity" (now you might want to stop here but I think a bit of noise is quite nice> select background layer > filter > add noise > tick gaussian and monochromatic and put in 6% > go back once again in filter > blur > gaussian blur > settings: radius 0.3 > now you can flatten your image and voila you should have a nice lith effect!

Happy photoshopping!

Actions

1. open one image
2. find the tap "actions" either next to history or > window >actions
3. by the actions tap is a little arrow on the right hand side > click new action > give it a nice name > click record >now just do everything you would do with this one image and that you want to do with all your others at a later stage > once finished: at the bottom of your actions palette is a play button and also a stop button > click the stop button >now: very likely you have created your new action in the default action set- just click "default actions" so it becomes blue > click the little down arrow once more > click "save actions" and then O.K.
4. put all the images you want to convert with the same settings into one folder
5. file > automate > batch > find your action you have just created > source: folder > choose: find the folder with your images > all the next little boxes do not tick > destination; decide where you want them > give them new names if you want to > and don't tick anything else > click O.K. and this should do the trick

Saves a lot of time!

Well I am kidding, but you sure know a ton o' stuff. However, my eyes glazed over at this point ... "left to your curve: 2; now find point 114 > click and put under output 130 (the easiest way to do this is just to click somewhere above the last point on your curve and then move that point until you find 114) > find point 190: output 211 "

Methinks Photoshop Elements was made for moi. Simple ... just like me.

Want to look twenty years younger? Want your friends/ partner to think you are the greatest photographer in the world?
Well here it comes: the skin and anti-wrinkle treatment:

open your portrait > duplicate the background layer (ctrl – J) > filter > blur > Gaussian blur: put 20-25% in the radius (don’t get a shock- we are not finished!) > layers palette: lower the opacity to 40-50% > layer > layer mask > hide all > choose a soft brush and white as foreground colour and start painting over the wrinkles/ blemishes or the whole face leaving the eyes/ eye brows and lips out (or anything else that you don’t want to have changed). Don’t think this is crap yet- we are still not finished!!! > if you are not sure what you might have missed: press the alt /option key and click directly on your layer mask in your layers palette: This is something many people don’t know!!! It will turn your colour pic into a black and white mask and you can continue painting directly on your masked image and touch up the areas you might have missed!!! If you click again on the colour thumbnail next to your mask you return to your colour image (cool!) Now some people want to just stop here and lower the opacity of this layer and are happy. Fine if it works for you (and it will already look fairly good!) but not for me... here is what you do if you want it to be perfect:

> hold ctrl/ command key and click directly on your layer mask: this will select the part that you have just worked on > click the background layer > press command/ ctrl – J and it will load the selection on its own layer > click the eye icons next to your blurry and background layer to hide both and just show you the selection layer > command - shift - U/ ctrl - shift – U (this takes the colour out) > filter > other > high pass filter > start with the slider all the way to the left and then slowly drag it to the right until some texture re-appears (might be somewhere in the 20-30s) > make your background and top layer visible again by clicking on the eye icons > now click you middle layer (the grey one) and drag it to the top of the layer stack >  change layer blending mode to soft light >  now this is important: lower the opacity until you are happy

Well done if you made it this far! This is something I regularly use in portraits and especially when it comes to weddings!

Happy photoshopping!

Stef. :P

P.S. Because I have not posted any tips the last couple of days...I throw another one in:



How to remove shiny areas on your subject:

This happens particularly when you use flash or uneven lighting. You subject might end up with hot spots on his/ her face as if they are sweating.

open your image > duplicate the background layer (ctrl-J) > choose the clone stamp tool > in the options bar at the top of your screen under “select” and “filter” change the mode from normal to “darken” and the opacity to around 30% > under “brush” left to “mode” choose a soft edged brush >  alt –click next to your hot spot on a clean area > paint carefully over your lighter spots > keep on sampling from different clean areas and brush carefully over your affected areas.

Job done!

Happy photoshopping!

duotones- tritones -quadtones

This is something that appears to scare the hell out of so many people for no reason at all!

Here is what you do:

1.Convert your colour image to a black and white image using one of the methods suggested in this thread. Once you are finished flatten your image.
2. image > mode > grayscale > image > mode > duotone > under type click either duotone/ tritone or quadtone and don't be afraid: YOU don't have to do much in the next step!
3. Let's assume you have decided for duotones: once the dialogue window opens click on the right hand side "load" (this is the cool thing you have a lot of presets saved on your computer and once you find them you are pretty much sorted!) Under "Look In" (at the top of your window) navigate to:  C: / Program Files/ Adobe/ Adobe Photoshop CS (what ever your number is)/ in that folder: Presets/ Duotones: here you will find "Duotones" "Tritones" "Quadtones".

In our case where we have decided to convert to duotones therefore we need to choose "duotones". Here we find a couple of subfolders- choose anyone of those and any setting inside and click load.

Voila! You are finished with your first one!

To see good comparisons- make a snapshot of your conversion by clicking the little camera icon under your history palette- go back to your greyscale conversion and start once again!

You can get numerous toning effects this way and it's up to you to decide which one works best. Once you are comfortable with these conversions you can fine tune them by clicking next to your "inks" in the duotone dialogue box and playing directly around with the curves displayed.


Have fun- it is simple!

Happy photoshopping

Stef:

I wish I had more time to follow up on your helpful instruction. (I really have to become retired again.:))Even tho I have E6 v CS3, some of this still works and in any case the concepts are what are important--there are sometimes more than one way to achieve similar effects.

You are keeping a record of all of these techniques, right? Or they are already written down somewhere in all of your stacks of computer folders, right? (You are not typing all of this from scratch are you?)

Soooooooo ... there must be a list of "top twenty" processes..or maybe 50 processes. Any chance you could put the "Top XXXX" into a single document and convert to a PDF and make available online? A combo of words and screen-capture images showing what's going on....

Now maybe you are working on this anyway with a view to selling an online book one day--or  a real hardcopy book ...so naturally that would be harmed by my suggestion.

Just a thought.

Cheers!

I have no such list. As said I really just quickly put down what I am working on. Guess everybody interested can just copy paste the tips into their own document and sort them. I am aware that some of the tips are all over the place- black and white tips (and there are more than one) are not in on go but on different pages in this thread. Anyhow- for people interested- they can start their own list by copying the relevant and interesting tips in their own lists?

Yes most if not all of these tips also work in Elements but it would take too much time for me to "translate" them into Elements language. As you said rightly it is much more about showing that these things are possible and you then have to experiment with it. ;)

Tip for reducing noise:

One easy way in Photoshop is to use the despeckle filter on the individual colour channels

(a) open you colour image > zoom in to 100% > copy your background layer
(b) in the layers panel > channels > now click on the individual channels and check which ones are the worst (might be more than one!) > leave that channel highlighted and go to > filter > noise > despeckle > click on RGB > click on layers > sharpen as you like

You might have to run the despeckle filter more than once and perhaps on more than one channel. It will make you image softer. When you sharpen the image be careful: use on of the sharpen methods in this thead. The reason why you copied the background layer is that you can reduce the opacity should the despeckle filter be too strong.

Hope this is useful?
Happy photoshopping!

Very quick way to tone your images:

(a) open you colour image
(b) create a new layer: > layer > new > layer
(c) choose the eyedropper tool > double click on the black and white swatch in your tool palette > choose any colour you like
(d) edit > fill > use foreground colour
(e) in layers palette set blending mode to colour
the next step is optional:
(f) click on background layer > new adjustment layer > hue saturation > play around with the hue and the saturation sliders

Voila you have a duotone image! Very quick indeed!

Faking Infrared

(1)
channel mixer method
make a copy of your background layer > use a channel mixer adjustment layer for this conversion with the following settings: red -50/ green 200/ blue -50 with Monochrome checked. If you have a lot of sky in your image you can also try: red 0/ green 200/ blue -100. You can also try red -70/ green +200/ blue -30 (It is important that you start with green +200 and leave it at that number) > go back to your background copy layer > click channels (next to the layer palette) and highlight the green channel > apply gaussian blur to that channel only: start with something around 5 pixels > click immediately after the last step > edit > fade filter with the following settings: 25% opacity; change the blending mode to screen.


(2)
If you prefer to use a black and white adjustment layer:
make first a copy of your background layer > add a black and white adjustment layer with the following settings: green +300/ cyans +150/ yellows +150/ red 0/ blues -40/ magentas +30 > go back to your background copy layer > click channels (next to the layer palette) and highlight the green channel > apply gaussian blur to that channel only: start with something around 5 pixels > click immediately after the last step > edit > fade filter with the following settings: 25% opacity; change the blending mode to screen.

With both methods you can at the end add some noise: filter > add noise> gaussian > click: monochrome > play around with the settings.

Hand Colouring

Some of you might remember the good old days of hand colouring black and white images? Well if not - let me tell you it was usually a huge mess and you needed quite a few black and white prints before you got it right (at least I did)
Here is what you do in Photoshop:
(1) open your image
(2) convert it to black and white (there are many different methods in this thread so just choose one...)
(3) make sure your image is in RGB mode: Image > Mode > RGB Color
(4) create a new empty layer: Layer > New > Layer > BEFORE you click OK change the "mode" from normal to color (second one from the bottom)
(5) now choose your brush tool and any nice colour and start painting! To choose a different colour just double click on the black or white little square in the tools palette

Modifications:

(a) Don't forget you can change the opacity of this layer
(b) Don't forget you can also change the opacity of your brush to get subtler colours
(c) You can also select parts of your image and use the fill tool: Edit > Fill

Important: Red Eye Removal

The above method also works very nicely with red eyes! Just choose a colour close to the original eye colour and paint on a separate layer (which needs to be in colour mode) and voila a nice way of getting rid of red eyes!

Hope this is useful?

Happy photoshopping!

I must be in a very good mood as I am giving you the third tip today! Guess quite a few of you have shot portraits but the catch lights were missing? Catch lights can make the difference between good and very good portraits.

Now here is how it goes:

(1) open you portrait
(2) create a new empty layer: Layer > New > Layer > just click O.K.
(3) take a very small fine brush and zoom into one of the eyes
(4) for a colour choose either white or something very close to white (double click the black and white swatch in your tools palette and choose your colour)
(5) paint one catch light into the one eye you have chosen
(6) now- either choose the blur filter on that layer (blur it a tiny bit) or perhaps easier: choose the smudge tool from your layers palette: it looks like a tear drop and smudge your catch light a bit
(7) now here comes the cool thing: how on earth do you get the same catch light in the other eye??? Just duplicate the layer where you just painted on and move it over the other eye! Layer > Duplicate Layer > choose the move tool (it is the top one in your tools palette and looks like an arrow) and move it over. Flatten the whole thing and bingo you have got two catch lights!

Hope this is useful?

Neutral Density Gradient Filter

How often does it happen that you end up with an image where the foreground is exposed correctly and the sky is to light because you have forgotten your filter set at home or don't have one ;) Well here is what you can do to remedy the situation...
(1) open your image in photoshop
(2) make sure the foreground colour is black
(3) Layer > New Fill Layer > Gradient > just click OK
(4) now the gradient fill dialogue box opens: tick at the bottom: reverse and align with layers > DO NOT CLICK OK YET! > double click directly on the gradient in your dialogue window and it will open another dialogue window > now you will see "little" gradients at the top and one big black to transparent gradient at the bottom. Over the bottom one on the right hand side is a little white thingy that looks like a house on its head > click this one with your mouse and drag it to the left > let go of the mouse to check your image: the black to transparent gradient that went all the way from the top to the bottom of your image should slowly lift towards the top. If it's not enough drag the little white "house" further to the left until it lines up nicely between sky and foreground. (Don't forget you have to let go of the mouse to see the difference!!!)
(5) click O.K. once happy and click O.K. again to close both dialogue windows > now you have two layers on top of each other. Make sure the top one is activated > set its blending mode to overlay and you are done!

Fine tuning
The effect is not strong enough for your taste? Click on the top layer and drag it to the bottom of your layers palette over the symbol next to your rubbish bin to duplicate the layer. Now the effect might be too strong so just lower the opacity of that very top layer before flattening the whole thing.

Hope this is useful?
Happy photoshopping

Red Eye Removal

This is a really fantastic way to get rid of red eyes and very quickly! It's a tip that I did not know until lately- please give it a try- promise you will love it!!!

(1) open your image in Photoshop
(2) duplicate the background layer
(3) in the layers palette click on channels > highlight the green channel > select > all > edit > copy > highlight the red channel > edit > paste > highlight RGB channel > go back to the layers palette
(4) go to layer > layer mask > hide all
(5) now you just need to paint with the paintbrush and the colour set to white over the pupil and voila you are done!!!!

Why does this work? The green channel does not contain any red- if you paste this over the red channel the red eyes will be eliminated! Why am I soooo excited about this tip? Well imagine you have a group picture with moe than one person and ALL have red eyes for some reason- you save yourself tons of time as you only need to copy past the green channel once and then just paint over all the eyes instead of having to select them individually!

Have fun!

Happy photoshopping

Fother- thanks for your kind comments! Good to know that you appreciate it!
Here is right the next one:

Skin Smoothing
Quite useful if you want to stay on good terms with your mother-in-law, spouse, girlfriend to be...as it is a very subtle way of making you look good:

(1) open your image- do all the usual adjustments first (levels... removing of blemishes...) the next step is the very last one!
(2) duplicate the background layer
(3) Filter > Noise > Media > set the value to about 8 - 10 pixels
(4) Set the opacity of this layer to about 50%
(5) Layer > Layer Mask > Hide All
(6) Set foreground colour to white, choose a brush with hardness set to 0 (just click the downward arrow next to brush at the top of your screen) > click on the top layer and there on the right on the black square in other words activate your layer mask > paint with white over the face leaving the eyes out. You can change brush size by clicking the left or right square brackets on your keyboard.

If the effect is too little just adjust the opacity of that layer until it feels right! If you need a stronger effect and you can't adjust it via opacity just set the media to 12 or higher. Voila a very happy customer!

High contrast and slightly coss-processed look

This can be highly effectiv in fashion shots or just for fun:

(1) open your colour image and make the usual adjustments (levels/ curves/ removing spots and blemishes...)
(2) duplicate your background layer
(3) convert this duplicated layer to black and white using whatever method you prefer (plenty of suggestions at the beginning of this thread)
(4) Image > Adjustments > Levels => increase the contrast by moving the black and white sliders inwards
(5) set the blending mode to overlay
(6) reduce the opacity until happy
(7) flatten image

Voila you got a fashion portrait.

Happy photoshopping!

I own a few books on "Photoshop how to do's", but your tips are very clear and precise. They are actually better than most of the tips in the books. (Perhaps that comes from your intuitive knowledge gained by teaching these subjects).

I want you to know that we all very much admire your willingness to share your knowledge. You are a goldmine of information. Thank you very much.

Ascot- by all means please do so. Unfortunately the tips in this thread are not in any particular order- something I wanted to talk to the moderator about at some point in time. Perhaps there is a way for me to re-order them by a-z. Once there are more and more tips you guys will have to look through many pages of tips before you can find what you are looking for. If that would be possible than I could always "insert" by alphabet a new tip and the whole thing would have some kind of order?

I always post a tip when I come across a particular problem either with students or myself. I don't intend to put up tips that cover too much of the basics. Please don't misunderstand me- this is not to ignore "beginners" at all but there are many very good books out there you can buy that will teach you the basics. (I know that as I am reviewing most of them!) What is really missing are the tips that go beyond the basics- kind of "advanced" tips- something where most people with some knowledge of PS would say (hopefully!): "haven't heard that one before..." To give an example the one with the red eye romoval is fantastic and I did not know that one until lately! It saves tons of time and is soooo simple! From now on you can honestly forget the "red eye removal tool". These are the tips that I think you can not find everywhere?

Anyhow- I am glad you use them and enjoy them! I started once with that stuff many years ago and am still grateful to people who taught me the one or other thing on my journey. As they say "what goes round comes round". If everybody would pass on a bit of their knowledge that would be great. I though the other day perhaps we can do some more sticky threads- such as "secrets to macro" (Liu!!!); "secrets to infrared" (Rob!!!); "secrets to lightning"...???

I end this post with my personal motto (following General James Doolittle (1896-1993) U.S. Air Force):

Quote:
We were put on this earth for one purpose, and that is to make it a better place. We should, therefore, be contributing members of society. And if the earth, as a result of our having been on it, is a better place than it was before we came, then we have achieved our destiny.

Not that I for one moment think I can do that- but I will try me best ;)

So as usual- happy photoshopping!
Stef. :P

One other way of doing it Stef would be to have a seperate stickied thread at the top of the page with the tip titles in and then when clicked on opens up a new window and it takes you to that particular tip (if its possible)



I could do an article on Infra Red if you like ???
Give me a few weeks and i'll get one done.

Rob- that would certainly help me! But on the other hand it might be easier for you (at least it is for me) if you just have a sticky topic and whenever something crosses your mind you can add it? Sample images of which I guess you have many and the how did I do it?
Well this is not for me to decide- guess we need to discuss this with the admin ;) Guess we should make an extra thread for it before we discuss in in length here in the PS tips?

OK, I'm sure this has been posted before, but just in case it hasn't... (and I've only just discovered this!)

When using the B&W filter in CS3, instead of using the different colour sliders, did you know that (with the dialogue open) you can just click on parts of the image and drag it right (to lighten) or left (to darken) - which basically drags the corresponding slider (of the colour below where you clicked)?

As I said, I didn't know until today !!!  ;)

How to size Photos for the Internet.

If you wish to prepare a photograph for submission to the [Monthly Challenges] (http://www.dynaxdigital.com/index.php/board,15.0.html) [Photo Critiques] (http://www.dynaxdigital.com/index.php/board,28.0.html)[Images to Share] (http://www.dynaxdigital.com/index.php/board,9.0.html) or to any other board, here is how it’s done in Photoshop, Elements is probably similar. Not sure about other programs.

NOTE:
This method will strip the exif data from your photo. If you wish it to be present, then use this method. (http://www.dynaxdigital.com/index.php/topic,4197.msg38846.html#msg38846)

1) After you are finished modifying and tweaking your photo, Go to >File >Save for web.
2) A new window will open with your photo shown full size. Click >Image Size. The size information of your photo will appear in the box. See Pic#1.
3) Change the >width or the >height (whichever is the largest) to 800.
4) Click >Apply.
5) Go up towards the top of the right side, you will see a tiny double arrow to the right of Preset. Click this Arrow and a context menu will open. Choose >Optimize to file Size. A small window will open.
6) Enter 150 (this has now been changed to 200) in the >Desired file size: box, leave current settings and current slice chosen. Click OK. The box will disappear.  See Pic#2
7) At the very top right side, click save and enter your desired file name and location.

Well just a very quick one- as I think I have not mentioned it before and I guess most of you know it...NEVERTHELESS it is very useful:

Levels adjustments

Should you ever use levels instead of curves and you move the black or white little sliders inwards until they are under the beginning of the histogram- hold the alt/apple key down while moving that slider. The image will either turn completely black or completely white. Keep moving the slider in until you either have the first black or white point turning up in your image and this is where you should stop moving. Often this point is further in than the "foot" of the histogram and t is the optimal point for contrast.
Hope as usual that this helps the one or other of you!
Happy photoshopping

Sloppy Horizon?

You are not sure how to correct a sloppy horizon in your wondfull landscape images?
1. Open your image
2. Choose the ruler tool (hidden under the colour picker in your tools palette over your hand tool)
3. Click somewhere where it should be straight and drag along the line which should be straight (keep the mouse clicked while dragging!)
4. Now here comes the cool part: Image > Rotate Canvass > Arbitrary > just click O.K.
5. Voila!!! Your image is straight and you just have to crop it!

Clever- eh?

Hope this helps?

How to emulate filters (This is the answer to a request by Ascot and follows a discussion between mainly Springtide and myself in another thread: http://www.dynaxdigital.com/index.php/topic,4772.msg34325.html#msg34325 (http://www.dynaxdigital.com/index.php/topic,4772.msg34325.html#msg34325)

Option I
Now let's assume for one moment you did download the Lee filter swatches from somewhere- one of the easiest ways to emulate a particular Lee filter (if not completely correct nevertheless close!) is to do the following:

You can just open you image than open your Lee filter (the one you have hopefully saved somewhere on your harddrive  ) and do the following:

1. click on you lee filter -> ctrl +c (=copy)
2. click on your image -> ctrl + V (=paste)
3. edit -> transform ->scale -> drage the handles until the lee filter is covering your whole image
4. set the layer blending mode from normal to colour and reduce the opacity to around 25%
Please keep in mind though- real Lee filters are obviously different than colour swatches as they are made of glass and usually in front of your camera ;)

Option II

This is if you don't have the swatches:
1. open you image in PS
2. layer > new adjustment layer > photo filter > click O.K. => a new dialogue window will open
3. Now you have two alternatives: (a) you try one of the presets: the easiest is to highlight the top one and then just scroll down by using the arrow keys on your keyboard paying attention on the effect that particular filter gives you with your image. Do not forget to play around with the density slider as well - to get a more subtle effect!!
(b) Here it gets interesting and the Lee filters come into play: In the dialogue box instead of choosing the presets > tick "colour" => your cursor becomes a colour picker (!) > double click in the little colour window > now you can choose any colour BUT the cool thing is: you don't need to choose a colour from the dialogue window that opens but you can choose ANY colour- also one from a colour swatch that you have downloaded from the Lee website or even another photograph!!! (Just see how the colour in the little window changes accordingly to where you used your colour picker!)
Don't forget again to play around with the density slider.
Voila you should be done!

For Advanced Users:
The above CAN get more complicated if you want to have 100% the real Lee filter effect: what you would have to do is take two images of the same object in the same light conditions- one with the Lee filter on the other without. Now you open both up in PS next to each other. Click F8 or Window > Info > at the same spot in both of the images and measure the values for RGB in the info palette. Now you will know how much warmer/ cooler/ redder/ greener...the one with the Lee filter is compared to the one without. Now it gets tricky: once you know these exact values you have two options...(actually many many more as usual... but let's keep it simple ;) ):
(a) you can make a colour balance adjustment layer and play around with the sliders until you get exactly the same values as in the image with the Lee filter and save this setting for later use in form of an action. (You could also take curves/ levels or pretty much  any other adjustment layer - they are more or less all able to do that)
(b) you could follow step one from above and at first take a photofilter preset that comes close to the desired effect and play around with the density until you get the desired values- don't forget you can stack the photofilters as well(!) (In other words you can use more than one photofilter adjustment layer)
(c) and just for the fun of it- I just throw in another option: you can use the match colour command under image > adjustments > match colour and save the statistics of the Lee filter image for future use to match with all your images... guess this leads a bit far...

I don't want to go one here (which we easily could ;)) just in case I scare people away- keep in mind this was a request (!). If you really need/ want to know more or something is not clear- just put it under the request section and I promise you we go a level (or two or three... ;)) up...

Hope this helps?

How to size Photos for the Internet and keep your exif data embedded.

If you wish to prepare a photograph for submission to the [Monthly Challenges] (http://www.dynaxdigital.com/index.php/board,15.0.html) [Photo Critiques] (http://www.dynaxdigital.com/index.php/board,28.0.html)[Images to Share] (http://www.dynaxdigital.com/index.php/board,9.0.html) or to any other board and keep your exif data embedded, here is how it can be done in Photoshop, Elements is probably similar. Not sure about other programs.

NOTE:
Be sure that this is what you really want as some exif data may contain personal information, such as your email address, home address and your name. If you do not want this information to be available to users of the internet, then prepare your photo using This Other Method (http://www.dynaxdigital.com/index.php/topic,4197.msg37126.html#msg37126)

1) After you are finished modifying and tweaking your photo, Go to >Image > Image Size. A new dialog box will open. (See Pic one) Ensure that 'Constrain Proportions' and 'Re-sample Image:' boxes are checked and one of the Bi-cubic methods are chosen. Change the >width or the >height (whichever is the largest) to 800. Click 'OK'.

Pic one.
(http://i107.photobucket.com/albums/m297/gbruce40/Picone.jpg)

2) Go to >Edit >Convert to Profile. In the box that opens (See Pic two) ensure that 'Profile' is sRGB IEC61966-2.1. Click 'OK'.

Pic two.
(http://i107.photobucket.com/albums/m297/gbruce40/Pictwo.jpg)

3) Go to >File >Save As and in the dialog box, check the 'As A Copy'. Click 'Save'.

4) In the JPEG Options window that opens, (See Pic three) ensure that 'Preview' is checked and move the slider until the file size is less than 200Kb. Click 'OK'.

Pic three.
(http://i107.photobucket.com/albums/m297/gbruce40/PicThree.jpg)

Thats it. When posted, your picture will contain all the exif data that is in the original file.

I was wondering if there is a way to correct barrel-distortion or to lessen or increase this effect (on pics taken using a fisheye lens) in Photoshop 7?

to correct barrel-distortion in PS 7

In the newer version of PS we now have something called filter > distort > lens correction which works wonder once you start playing around with it. Not sure since what version of CS that filter exists???

Another simple option is:

1. Layer > New > Layer from Background (or just double click the background layer to convert it to a layer)
2. Edit > Transform > now: try perspective first (but the other ones work as well)
3. Pull the corners of the image a bit out so that you can see all corner handles. Now start with pulling out the bottom right and left hand handles until the perspective is right- or depending on the problem with your perspective use the top left and right one
4. Flatten the image and you should be done.

BTW:

This is also a good trick if your foreground interest object turns out to be too small. You can enlarge it this way and then blend the duplicated layer together with the original background layer.

Hope this helps?

How to clean up a studio background?

Guess you all had this at some point: you shoot a model in front of a white studio background with sophisticated lighting and then realise that the lighting was not that good… Instead of an even super white background you end up with some blotches or shadows- sounds familiar???


Well here is what you can do:

“Replace Colour” Command

1. With your image open: Image > Adjustments > Replace Colour => click on the white background. Now hold shift and keep on clicking on all the offending parts. You will be able to tell from the preview window whether you got them all. Use the fuzziness slider to fine tune the results.
2. The only thing you have to do now is to move the lightness slider all the way to the right.
3. At a very last step once you are done with this- open up curves or levels and adjust the contrast of your model by either moving the curve in the middle slightly upwards (assuming black is on the left hand side) or the middle slider of the levels command.

Voila you should be done! Background white and photographer happy!

NOW: Never a tip without another one! If you decide to change the background colour completely- nothing easier than that! Just play around with the hue and saturation sliders as well while keeping lightness at 0. You can then adjust the lightness of your particular colour- but colour comes first!

Hope this helps?

Macro Shot with great depth

I came across the following tip today and thought it might be of interest to some of you?
When we shoot macro shots we usually have a very shallow depth of field. If you want to increase the "in-focus area" than you have to start with shooting more than one image of the same object. In each of your shots you shift the focus point slightly. I.e.: you start with focusing on the first petal of a flower- the once closest to you. Then you focus on sth. slightly behind the first focus point and so on. At the end you might have something such as 6 images with differing focus points. Now the question is how to combine them in PS?

Here is what you do in CS3:

1. file > scripts > load files into stack (use the browse button to search for your files) > make sure: "attempt to automatically align source images" is ticked > click O.K.
2. The images will be loaded as a single layer file. Switch of all layers by clicking the eye next to them just leaving the bottom on turned on. Create a layer mask and paint with a soft large brush in black over the parts of this image that are not in focus to hide them. If you make a mistake change the colour to white and paint over it again
2. Now turn the bottom layer's visibility off by clicking the eye next to that layer and turn the visibility of the next layer on. Do the same procedure of step 1 again with all layers using layer masks and painting with black onto them.
3. At the very end flatten your image. You might see some overlappin at the edges. Use the crop tool to get rid of them.
4. Use levels or curves to adjust the contrast
5. You might want to increase the saturation with a hue/saturation adjustment layer
6. Finally sharpend the image to your liking

Hope this helps?

How to add a signature to your images?

1. sign with a black pen on a white sheet of paper and either scan your signature into Photoshop at 300ppi or just take a photograph of it making sure your writing is in focus
2. once that signature is in PS: open the levels palette in Photoshop (image > adjustments > levels) and drag the left (black) slider to the right and the right (white) slider to the left until the writing is pure black and the paper is pure white.
3. take the rectangular marquee tool and make a selection around your signature
4. edit > define brush preset > save the brush as your signature
5. open the image you want to add your signature to > create a new layer > select the colour you want to have by double clicking the foreground colour swatch > search for your brush under the brush presets and add your signature. Using the backet keys [ or ] allows you to alter the brush size.
6. you can now lower the opacity of the signature layer or even add some layer blending effects. These effects could be save as an action for later use.

As usual: a variation:

In effect you can create a whole image as your personal signature doing whatever you want to it. At the end once the image layers are flattened you can do the following: select all and do step 4 from above!

Hope this is helpful?

Blown out Highlights

This is a quick tip for rescuing blown out highlights- especially when shooting in Jpegs:

1. open your image in PS
2. Image > Adjustments > Levels: here you have two level adjusters- the inputand the outputsliders. Use the output slider for this exercise and where it says 255 put something around 245 in. This will make sure that when you print the image that you still have some graduation in the white parts of your image. Can work wonders with clouds in the skies!

Three Step Sharpening: capture sharpening/ creative sharpening and output sharpening

Now when it comes to Photoshop there are always a hundred different ways for doing things and much worse a hundred different opinions about what is best ;)

This is one possible way of achieving the best result...

It is sharpening in three steps. Some people would say " don't sharpen at all in-camera and/or in the RAW converter but do everything in Photoshop.

Now I suggest you try the following and make up your own mind ;) : Make sure you look at your image at 100%!!!
1. Do it as you always would do it so you have a chance to compare the results! Make sure thought that you work on a duplicate of the original.
2. Now trythis:
a) make sure you don't sharpen your image in RAW but just open it up in PS
b) before you do any adjustments do this: filter > sharpen > smart sharpen > tick "preview" and "basic"; amount 125%; radius 1; remove: lens blur; untick "more accurate" > click O.K
c) NOW do all your usual adjustments. Once finished- flatten you layers should you have any and make a copy of your background layer: layer > new > layer via copy (or: ctrl+J)
d) smart sharpen again with the same settings as under b
e) layer > layer mask > hide all => the effect from the last step will completely disappear
f) take a brush tool with white as foreground colour and paint carefully over the parts that you need sharp (eyes, flower petals...) and leave skin ...out
g) once this is done > flatten your image once more > now resize it to your final output size and should you want to print it than believe it or not: sharpen once more as under b just this time put 25% under "amount"

Give it a try and let me know what you think!

How to replicate a tilt-and-shift lens or: How to make  a scene look like it is a model

This is just something the one or other of you might want to play around with...

For Elements or PS:

1. Make sure you start with a full adjusted image. You should have corrected perspective if needed and levels/ contrast/ curves/ colours...
2. Duplicate the background layer and apply filter > blur > gaussian blur > set it to 10
3. Take the rectangular marquee tool and make a selection around the part you want NOT blurred. Then: select > modify > feather: 70 pixels
4. Create a new level adjustment layer and just click O.K. without changing anything
5. Click on the mask sign (it is the square to the right on the level adjustment layer) > ctrl - I/ Opt - I
6. Drag the layer UNDER the blurred layer and hold the alt key while clicking between the two layers (top and second)
7. To refine the edges: click once more on the layer mask of the levels adjustment layer and paint either with black or white
8. Click on the top layer > create a hue/ saturation adjustment layer and boost saturation to somewhere around +20-40
9. Create a levels adjustment layer and boost the contrast
10. Click on the background layer (the bottom one) and apply sharpening before flattening the image

Hope you had fun?

This follows a question in another thread.

How to apply texture to an image

1. Open your image you want the texture applied to in PS
2. Open the image with the texture (In future you might want to think about shooting textures as well and build you own image bank- I have a   
    couple of thousands by now ;) )
3. Click the image with the texture to activate it. Make sure that both images are the same orientation (makes it easier)
4. Ctrl + A > click on the image you want the texture applied to > ctrl +V (cmd for apple)
5. edit > transform > scale > if you hold shift +ctrl at the same time and pull one of the corners you can adjust the size of the texture layer without changing its perspective.
6. You have now the texture layer on top of the image layer which you can't see
7. Now set the layer blending mode either to darken/ multiply/overlay/soft light/ and change the opacity of that layer to somewhere around 50%

Tip: any of these layer blending options might work. The easiest is to first lower the opacity to 50% then click in the layer palette where it says "normal" so that normal changes to blue colour. What you can then do is just scroll down through all layer blending modes by using the downwards arrow next to your number pad on your keyboard!
Voila- just should find easily the right blending mode in a couple of seconds!

Faking Infrared (IR)

It is not a replacement for real infrared shooting but can work wonders:
1. Open you image in PS
2. Layer > New Adjustment Layer > Channel Mixer
3. Use the following settings: Red +100; Green +200; Blue -200
Now: Don't scream yet...
4. Use the constant slider at the bottom and adjust the image to your liking - this point 4 is what most people don't know but you do now ;)
5. Click O.K and flatten if happy.

Voila you should be done!

Cropping

This is a good one! Most of you have used the crop tool in PS- haven't you ;) Well there is another very neat way of cropping an image particularly if you want a fixed ratio...

1. Open you image in PS
2. Select the "Marquee" tool (It is the second tool right under/next to the arrow tool)
3. Make sure the options palette is visible: Window > tick Options
4. In the Options palette at the top of your screen > Change the "Style" to "Fixed Ratio" > If you want a landscape image with the ration 3:2 than just put 3 under width and 2 under height
5. Use the marquee tool on your image (don't forget you can reposition your marquee by moving the cursor into the middle of you marquee)
6. Once done > Image > Crop

Voila you should have an image with the ratio 3:2 which can be very useful for printing!

Hope this helps?

I'm in a good mood today- here is tip number 3 for today:

Blown Out Highlights

This is for advanced users and you should experiment around a bit with the following:
1. Open you image in PS
2. Duplicate the Background Layer
3. Image > Adjustments > Invert
4. Lower the opacity to somewhere around 5-10% and set the layer blending mode to darken
5. Now this is where the advanced user comes in: mask the parts of the image that you don't want to have darker or just erase parts of that layer so that the lighter backround can show through

Tip: if it is a sky which is blown out you might want to use the gradient tool set from black to white and use it on the layer mask of the inverted layer. Alternatively: you might want to fill the layer mask with black and then paint with white on the mask where you want the darker parts to appear (change the opacity of the brush according to how strong the effect should be) Any questions to this please use the other thread and I am more than happy to explain a bit further. This is just a tip for you to experiment with!

Happy photoshopping!

And another one...

Adding Contrast

This is a very neat one- I promise!

1. Open you image in PS
2. Duplicate the Background Layer
3. Image > Adjustments > Invert (Ctrl/ Cmd + I)
3. Set Layer Blending Mode to "Overlay"
4. Now here comes the trick that not many know... Filter > Blur > Gaussian Blur > set it to around 50% (Be careful not to set it too high of you are going to have halos!)

Voila a more contrasty image!

Happy photoshopping!

How to blur a background

Ever wanted to throw something out of focus in the background but did not know how?

(1) open image in PS
(2) duplicate background image
(3) click Q (= edit in quick mask mode)
(4) choose the gradient tool (make sure reverse is ticked/ and black is the foreground colour)
(5) hold the shift key and click somewhere in the middle of your image; drag the cursor just about 1 inch towards the top of the image (the longer you drag the softer the gradient of the blur will be; you could also just start at the bottom and go all the way up => experiment with this one!)
(6) if you let go – the top of the image should be reddish- if not don’t worry => click: Q again => you should now have a selection at the TOP of the image. If not do the following: click select > inverse
(7) filter > blur > Gaussian blur > try something between 10 and 20 but don’t overdo it!
8. ctrl/cmd + D => deselects
(9) layer > layer mask > reveal all
(10) choose black as foreground colour: now take a soft brush and paint over the parts that you want to have in focus; towards the border of your subject (i.e. hair) lower the opacity of the brush (and that last part is the trick to keep it realistic! You might need to work around the hair/ face with an opacity of 10%) Take your time with step 10!
(11) you are more or less done- if the effect is too strong- lower the opacity of the blurred layer until happy

Hope this helps?
Happy photoshopping

Toning your images or: Gradient Map toning

This is without the best way to tone your images:
1. open your image in PS
2. click D on your keyboard to set the foreground colour to black
3. Layer > New Adjustment Layer > Gradient Map > O.K. > double click directly on the gradient map > this opens the gradient editor
4. click somewhere under the black to white gradient gradient => this will add a colour stop
5. click directly on that stop itself and choose any colour you want from the colour picker. Keep clicking or moving the vertical hue slider
6. click O.K. 3x
7. you can now alter the opacity of this layer to your liking!

Variation:
Instead of adding one colour stop as in step 4 you can add 2/3/4... and click each time on the stops to choose a colour => this way you can "rainbow" colour your image...

Hope this helps?
Happy photoshopping!

Alternative way of Dodging and Burning (non distructive).

[not sure if Stef has already shown this, but can't find it so will post..]

1. Open your image in PS
2. Create a new layer
3. Edit > Fill > 50% Grey & 100% Opacity
4. Select the new layer and change belending mode to 'overlay'
5. Use a feathered brush on the 50% grey layer of either white of black for your dodging and burning, varying the opacity for the desired effect.

This makes it obviously easiler to undo any mistakes without worrying about the saves history.

Post by: Stef. on June 17, 2008, 05:51:18 PM
What Springtide suggested is very true- but as said at various stages always do everything on a copied background layer!
Thanks for the very important reminder! If you do dodging or burning- either do it as Springtide suggested or just copy the background layer.

Like your idea! No offense taken but the idea was to sharpen edges. (Step 5) This is particularly useful for for instance noisier images where sharpening needs to be applied very carefully. I have so far suggested various ways to sharpen an image for different occasions (at least 4 different ways)- the above one being one of the safer methods. My personal experience over the years has been that there is no such thing as one sharpening method which suits every image and sometimes it is useful to go the long way 'round. Certainly both of the sharpening methods have their values as you say there is more than one way to do things but I do think that in the above case the sharpening methods differ in the end result and can not really be compared. I would hope that your method is seen as a new/other way of sharpening to mine and not as an easier but same version to the one you have quoted. Sorry for this long blurb- we should try to keep this thread free of comments- they should be done in the other thread as was suggested some time ago but you had quoted my tip and compared it to yours so I could not leave this without answer- as I repeat: I don't think they can be compared.
Glad to have you on board!

cmorrisse, I have added you're tip to the tip index. Thank you for your input, it is greatly appreciated. :)

As you say, it may be similar to Stef's but unlike Stef's tips, does not have the detailed steps that someone new to photoshop may need. That fact may contribute somewhat to the apparent shorter method and as Stef says "I would hope that your method is seen as a new/other way of sharpening to mine and not as an easier but same version to the one you have quoted.."

I can sympathize with Stef's need to answer your comparison with her method, she is our main contributor to these tips and does so with an unselfish vitality. With that in mind, I ask that we all try to appreciate that these tips are great for those new to photoshop, as they are to more experienced members and comparing them is counterproductive. Let's just enjoy the variety that they provide.

Thought you might want to hear from me again in this thread ;)

Noise Issues- and how to deal with them

Noise results from mainly six sources- some of which you can deal with before shooting you images:

(1)   Sensor Noise- all sensors produce some noise and this is one of the targets for manufacturers to keep noise levels down- not much you can do about it but choosing the “right” camera. This kind of noise becomes worse the more pixels are cramped onto a sensor
(2)   High ISO speeds: well what can I say- keep the ISO as low as possible but still high enough to avoid camera shake. Try to use the “right” lights for indoors; use reflectors anything basically that increases the light levels so that you can keep the ISO down
(3)   Underexposure: make sure you expose your image so that the histogram goes as much to the right side as possible without burning out the highlights; you can have “spikes” very close to the right hand side of your histogram but if possible without “touching” the right hand side. Makes sense? This is important as noise is usually most prominent in the darker areas of your image
(4)   Heat:  keep your camera in the shade as much as possible; don’t let the camera body get to hot; take a cooler bag with you when travelling in hot countries; put a hat over your camera when mounted on a tripod for longer intervals... anything that keeps the camera cool!
(5)   Digital artifacts: again not much you can do about; it occurs mostly in fine graduations such as skies; it is a result of technology and you have to live with it.
(6)   JPEG artifacts: these occur through compression; if you shoot in JPEG mode shoot with the highest quality setting possible or even better raw

Now what happens when you have shot your images keeping the above in mind and trying to avoid as many noise issues as possible but you still have noise in your images?

Here is what you can do- just a couple of tips that might make your life slightly easier- in no particular order:

(1)   When you sharpen noisy images do NOT use “Smart Sharpen” as it has no threshold slider. Use: Unsharp Mask and set your threshold to a number between 6 and 12. Also in really problematic images: make a duplicate layer of your background, sharpen as suggested above and then either mask out or just delete part of that sharpened layer particularly in the areas where there is noise i.e. the sky. Alternatively you can select parts of your image first and then apply the sharpening filter only on those areas.
(2)   Do NOT over enhance your image with colour and exposure adjustments; again do these on a duplicated background layer and erase the parts where you have noise
(3)   Photoshop/ Raw converters/ any other post-processing program- they all have some kind of noise reduction feature or filters: be careful if you use them on your whole image it will soften the image. So here once again- make a duplicate layer of you background, then use the noise reduction filter and erase all the parts of your image that did not really need this filter. In worst case erase with a fine brush all the little parts that should be sharp i.e. eyes . Alternatively you can first select the problematic areas such as skies with the lasso tool; magic wand or whatever else you are use to using and then apply the noise filter only on those parts.
(4)   Finally there are some programs out there that work wonders when it comes to reducing noise. Just google and you’ll find many. Try them and see what works for you.

Hope this is helping at least some of you?

Colour Boost

Now the real ;) photoshopper does not work in RGB but in LAB colour- why? Well the short answer is: it's better! The slightly longer answer is: because you have not to deal with annoying colour shifts. And the very long answer- well that one comes in a different thread... (too lazy to explain right now and not sure it interests you anyhow?)

Here is what you do to boost your colours or even what you can do to reveal colours that you sawbut that are not in your image. (let's not forget: the eye can see more colours than the camera can and it can also deal with higher contrast than your camera can!)

1. Open you image in PS
2. Image > Mode > Lab colour
3. Duplicate your background layer
4. In the layers palette click on "channels" > click the a channel > Image > Adjustments > Levels > drag the left slider to approx. 80 and the right slider to approx 275 > click O.K. > now click the b channel and do the same (the slider should be just under the beginning of the histogram on the left hand side and the same on the right hand side) > click O.K.
5. Now in the channels palette click the lightness channel > Image > Adjustments > Brightness/Contrast (YES! not curves!) change the settings to your liking and click O.K. Then on the same channel: filter > sharpen > smart sharpen > amount approx. 100%; radius 1; remove: lens blur; untick "more accurate" > click O.K.
6. In the channels palette click LAB to reveal all colours and DON'T GET A HEARTATTACK- we are not finished yet!
7. In the layers palette: click Layers the next one to Channels and reduce the opacity of that layer to somewhere around 15-20% according to your taste.

It works a treat!

Polarising Effect

This is a very neat effect to simulate a polarising filter should you have forgotten this important accessory at home ;)

1. Open your image
2. Duplicate the background layer
3. Select "channels" in the layer palette and click the red one
4. In the menu bar click select > select all (ctrl/cmd + A) > edit > copy (ctrl/cmd + C)
5. Click RGB again in your channels palette > Image > Mode > Lab colour > click: "don't flatten
6. Click the "lightness" channel > edit paste (ctrl/cmd + V)
7. Click "Lab" again in the channels palette > image > mode > RGB > don't flatten >click on "layer" in the layer palette and select the top layer
8. Layer > layer mask >reveal all (or just click at the bottom of the layer palette the little white circle- this will apply a layer mask)
9. Click the layer mask to work on it > image > apply image: under layer -> choose "background"; under channel -> choose red; blending: multiply; opacity 100%; tick: "invert"
10. If the effect is too strong lower the opacity of that top layer if it is not strong enough duplicate that layer once more and play around with opacity before flatten.

Voila this should help the one or other of you.

Happy photoshopping

Aging image effect

Not sure for what you might ever want to use this but I was asked to demonstrate how to age an image. Now first of all this does not suit all images. Anything in the picture that gives away the fact that it has been taken today i.e the newest Ferrari... will give the effect away. It works well for landscapes.

1. Open image and duplicate the background
2. Go to channels and click them one by one through. You are looking for the one which gives the least clarity- quite often that's the red one. Make sure you select that one by highlighting it in blue- just click on it (the image will turn black and white) and just click on "layers"
3. Make an adjustment layer "hue/saturation" > click colorize and create a sepia effect (good start is hue: around 50; saturation around 25)
4. hold down ALT/Option and click the "create a new layer" button at the bottom of the layers palette; don't click O.K. yet! Set Mode to "overlay" and tick below that: "Fill with Overlay-neutral colour (50% gray)" > now click O.K.
5. Filter > noise > add noise > gaussian > tick monochromatic > choose a pretty high amount somewhere around 20-40%
6. Filter > blur > gaussian blur > 1 pixel
7. Add a level adjustment layer and pull both sliders (the black and the white one) inwards over the edge of the histogram AND move the black OUTput sldier to the right to about 20
8. Click the original copy of the background layer and add a slight gaussian blur
9. Add another levels layer and this time drag the midtone slider to the left to lighten the image
10. Click on the layer mask of this levels adjustment layer > choose the gradient tool (make sure it is set from black to white by firstly clicking D on your keyboard) > now draw a gradient to simulate fading
11. When happy > flatten the image > choose the elliptical marquee tool and draw a circle nearly over the whole image > click Q > filter > blur > gaussian blur > drag the radius to the right- approx. 50 pixels and watch your quick mask softening at the edges > click O.K. > click Q again and you have a softened marquee > select > inverse > image > adjustments > levels > drag the sliders so that the outside of your marquee gets darker/ or lighter depending on your taste.

That should do the trick!
Happy photoshopping!

Just was aksed this question somewhere else and thought it might be useful to put in here as well.

How to make large prints- or how to upsize and image

Make sure you do the following and don't ask me why it works -but it does and that's the most important thing...

a) go into image size- tick "resample" at the bottom of the page and make sure constrain proportions is ticked as well
b) put you size in iches into one of the fields (the other will change automatically) and put for resolution 360 (and yes I know - usually the perfect print resolution is 300 but just trust me on this one ;)) don't click O.K. just yet => where it says bicubic smoother ( best for enlargements) change this for bicubic sharper (best for reduction) - again just trust me...

You'd be surprise how big you can print that way and how sharp it is...

Best of luck and happy photoshopping!

Drawing attention to your subject

This is a really cool tip and works wonders with portraits/ flowers/ animals/ and yes Clive- birds! Should also work in Elements.

1. Open you image in PS
2. Do all the usual adjustments
3. When you are finished- use the elliptical selection tool (second tool of the top- usually hidden behind the marquee tool) and draw a selection around your subject and then invert the selection (select > inverse). Now all the surrounding of you subject should be selected.
4. Create a brightness/contrast adjustment layer and set brightness to approx. -30 (layer > new adjustment layer > brightness/contrast)
5. You will see a distinct lighter circle around your subject- don't panic!
6. Still being on this adjustment layer: > filter > blur > gaussian blur > set the radius to at least 100%
7. Voila it should look pretty cool!

Hope this helps?

Faking Infrared

I know we have dealt with infrared before but this is something new I came across the other day and very well worth mentioning!

1. Convert your image to black and white- one fast way of doing this is to go to the channel mixer and click under presets on "infrared".
2. Set the foreground colour to white by first clicking the letter D and then the letter X
3. Select > Colour Range > click on your image on a highlight such as the already whitish foliage > change the fuzziness slider to approx. 100
4. Select > modify > expand > 1 pixel
5. Select > modify > feather > somewhere between 10 and 25 pixels
6. Edit > fill > use foreground colour (white) > set the opacity to somewhere around 15-100%

This should deliver the glow to highlights, similar to the look of black and white infrared film. Cool eh?

Happy photoshopping!

Quick copyright stamp

(Note: this may have been posted here already. Apologies to Stef. if she posted this already. :-[ I could not find it. ;) )

This description is for Elements 6. It works in Elements 3 as well and probably in CS3 and 4.

When you want to add a uniform copyright notice to a lot of pictures this works well. You actually create a "brush stamp." The neat thing is you can "stamp" your copyright notice in critical areas of a picture. You can see samples of how I used it here:
http://photoshare.shaw.ca/messages/viewthumb/6398794269-1226550479-77013/parm/page/1/15/

Create a new blank page (ctrl N) and make it about 200 pixel by 50 pixels.

Select the text tool. You may have to play with a couple of font sizes. (For web-sized images with resolution set at 72, the 18-pt text works okay.) Don't worry about the text color for now. To create the ©, type <Alt>  0169. (Thanks Rob!) Note: you have to have the "num lock" activated ... you MUST use the numbers pad.

Okay, so now you have your copyright notice typed..maybe something like, © 2008 CAS. Make the text layer "active" by clicking the pointer arrow...it will now have lines and "drag points around it.

Then click Edit and select "Define brush" .. give it a name like "© 2008 CAS" .. or whatever.

Now, with a picture open in PS, click on the brush tool. Scroll down to the bottom of the brush tool palette and you will find your brush stamp that is your very own © stamp. Go crazy. You can pick different opacity and color.

(http://photoshare.shaw.ca/image/2/d/8/63987/brushstamp-0.jpg)

You can stamp it all over the place. I needed to do a few dozen FAST tonight. Voila. Warning! Just stamp once and fast. DO NOT drag the brush stamp .. it is a brush tool and will paint your © notice as well. ;)

You can warp the text (before saving the stamp brush) and generally do whatever you want. When you select the brush..change opacity and color if you wish.

on the topic of ©

my laptop wont allow me to do the Alt 0169 nor numlock nor ctrl alt C, this was annoying me, hate it when others can do stuff and i can't :D

so i googled and found this

Or, you could just use the "Character Map" which is a stand-alone program that can be found under: "Start" - "All Programs" - "Accessories" - "System Tools".

You can select different fonts, see it's key stoke short-cut, and of course, you can just simply copy-paste the character you want.

So now i can at least put a © on if i so desired ©ee :-)

Adding that 'shine' to a photo!  [useful for car pictures etc]

Very similar to the 'high pass sharpening technique', but instead of selecting just a couple of pixels (usually 2 pixels) for the high pass filter, make widen it up a little (say 8-10 pixels)

i.e. 

- Add duplicate layer
- Filter > High pass filter (select 8-20 pixels, but experiment)
- Select Soft light blend
- Adjust opacity to get the right effect!

e.g.

Before:
(http://farm4.static.flickr.com/3010/2980577913_4041da0aa6.jpg)

After:
(http://farm4.static.flickr.com/3279/3040597919_03122d32c2.jpg)

This was done with "15 pixel" High pass filter & 60% Opacity

Guys yes I will let you all know. BTW just a polite suggestion: can we discuss all these things outside the darkroom tips- or people will have to scroll through a lot of our conversations to get to what they are looking for?
Perhaps somewhere here:

Well - this thread 'wasted' a couple of hours!! ;) ;)
Many thanks to you all but especially Stef who has indeed written a book! I've nearly run out of paper ;)

wildieswife, if you go to this link (http://www.dynaxdigital.com/index.php/topic,5034.msg36875.html#msg36875) you will find an index to all stefs great tips and from others also. Makes it easier to find them, rather than printing them all out.

Please guys do me a favour and don't pass these print outs on to other people! They are meant (at least my part of the tips) as good will to the members here on the forum but not to the wider world. I am in the progress of writing a PS CS4 book...
Thanks Stef.

No fear- I only printed out because I find it easier on the eyes to read off paper and I assimilate it better too!

I'm sure you'll do well with the book .

Printer Settings

I thought I put this up here as well as these settings are very similar for all the different photographic printers. The main players in this field are Epson/ Canon and some HP printers.

Printing with Epson 2880 and Photoshop CS+: But this works pretty much the same for all other printers at least until step 2

file > print > use the following settings in this first dialogue box:

1. at the top right hand side it needs to say "colour management"; below that tick "document" under colour handling and this is very important choose: "Photoshop Manages Colors"; under printer profile choose the profile for your particular paper (if you have not the right one for your particular paper you can download them from the website); Rendering Intent choose "Relative Colorimetric"; tick "Black Point Compensation";

now to the left: starting again at the top:
Printer: choose your printer; directly under that the layout: landscape or portrait; you can choose to tick further down "scale to fit media" if you like;
now go back up on the left hand side where it says "page setup > click and a second dialogue will open that shows and interface which depends on your particular printer

2. go to the "main tab"
under "media type" check that it is the right setting for your paper; color: decide on whether this is black and white as the next steps depend on that!

for colour prints:
> choose colour; print quality: choose "quality options" put 4 in it and leave high speed on (there have been tests that showed it is not worth turning it off- for other printers please do turn it off) The numbers you put in under quality options change the dpis. 4 is a good choice IMHO.
> make sure that under mode it says "custom and off no color adjustment"; finally check the paper size and you can click print- you are done.

For black and white it is slightly different and I only put here what you need to change from color:
under color obviously put "advanced b+w"; under "mode" it will now highlight "color controls" > click the Advanced next to it: here you can set your toning and so on. I usually use the following settings here:
toning: neutral
tone: darker (works better for most)

The rest is playing around and I am more than willing to go into the more special settings should there be need for it?

The most important part of all the above is to set the printer to "photoshop manages colors and to make sure color management for color prints is set to off in the second dialogue box!!!

Correction of an Underexposed Image

Some time ago I psoted a tip about how to rescue underexposed images. This tip basically suggested to make a copy of the background layer > set the blending mode to "screen" and reduce the opacity.

Here is another way that I came across yesterday:

1. create a new empty layer over you background and fill the layer with white. This can be done by either: by first hitting D on the keyboard and then ctrl + Backspace or on Macs cmd + del
2. Set the blending mode of this white layer to "overlay"
3. Now just lower the opacity of that layer

Sometimes the one or the other method works better- so just give it a try.

Happy photoshopping!

Tethered Shooting and Import

This is not strictly a darkroom technique but I think it is worthwhile keeping it in this thread for future use.

You can shoot in tethered mode with Adobe Bridge and in Lightroom as Fother has very rightly pointed out to me in a pm. You can do this with the help of a combination of the software that came bundled with your camera and with setting Adobe Bridge in a way that it monitors the folder in which the images are stored by your camera's software. This is basically a way around buying a dedicated software program that is designed to operate in tethered mode. The only requirement is that the camera is connected to your computer via an usb cable and that obviously the camera is capable of shooting tethered.

This is what you have to do:

(1)
Connect your camera via USB to your computer > set in the camera menu under the settings no 2: usb connection to: "remote PC" > open the program "Sony Image Data Suite" on your computer > open remote camera control > under "save in" -> choose a folder and remember the name of it! (This is where the images a stored and this will be the folder Adobe Bridge needs to watch)

In the next step you need to point Bridge to the same watch folder as you have just set up under "remote camera control":  please do the following- and I assume that you want to see the newest image at the top of the content area in the Bridge window:

(2)
Open Bridge > click "view" > sort > choose "ascending order" (sorts the files in reverse order so that the newest is on top) > in the folder menu on the left hand side make sure you select the folder that you have assigned under camera control

Now all should be fine and once you start shooting with the remote control Bridge should update your files with the latest one appearing on top of your screen. You might have to re-arrange the Bridge layout a bit so it suits you- just play around with the layout of Bridge!

Hope this is helpful?

In this case not happy photoshopping but happy tethered shooting!
Stef.

Colour Range used as a selection tool:

Colour range is unfortunately completely underrated eventhough I consider it as one of the most useful tools in PS.

So where can you find it and what can you do with it?

Well go to: select > colour range.

What most people don't know is the following and this will explain what you can do with it:
When the dialogue box opens up- at the top it will say "sampled colors" with a little downward arrow next to it. Click that one. Now the interesting part here is not the colours at the top but the three last ones which say: highlights/ midtones and shadows. Now it might perhaps dawn on you where I am getting with this... these three options are next to brilliant! Why? Well just think of the following: you have an image that shows noise. Well where does it usually show noise? Yep- the shadows. Now just select with this tool the shadows and click O.K. You will see that all shadow parts of your image are automatically selected. How neat is this? Now you just need to apply either noise ninja on that selection or go to filter > noise >  reduce noise. Make sure you look at your image at 100%. Also: should there be parts selected in your image that you don't want selected than just click Q on your keyboard > make sure the foreground colour is white and use the brush tool to paint over the parts that you don't want to have selected and then apply your noise reduction.

What else can you do with that? Well tons of things!  You want to slightly darken only the highlights? (Bet you want that one regularly!) Well just choose the highlights in color range > click O.K. > then feather the selection by going into select > modify > feather > put about 2-5 pixels in there > and either use levels/ curves/ brightness to tone the highlights down. Now is this cool or not?

You want to increase the midtone contrast? Well again just choose the midtones and work with levels or whatever else tool you like on those midtones!

Please do tell me that this is fantastic! And admit that you have never used that one before ;)

Happy photoshopping!

Sharpening

This is a very neat way to sharpen images without accentuating noise. It is particularly good for stuff such as architecture but just give it a try and you'll see how useful it can be:
1. Duplicate your background layer
2. Filter > Stylize > Emboss > use somewhere around 2-4 pixels; play around with the amount but 100% is not bad; use the angle only if you have shadows in your image => try to match the angle with the direction of the shadows > click O.K
3. Image > Adjustment > Desaturate (if you don't do that you will introduce colour fringes!)
4. Set the blending option of this layer either to soft light or hard light and play around with the opacity of this layer

The following is important!

(a) Check very carefully your image at 100% to see that you have not introduced any obvious bevelling in particularly the highlight areas!!!
(b) The best use of this method is: to apply a layer mask (Layer > Layer Mask > Hide All) and then use a brush -> set the foreground colour to white by clicking D and then X on your keyboard -> now just paint over the parts that you want to sharpen. By playing around with the opacity of the brush beacuse you can strengthen or weaken the sharpening effect by doing this.

It works wonders on eyes in portraits! Best of luck with it and as usual:

Beauty Tip: How to smooth skin blemishes with the help of Camera RAW

Just came across this tip yesterday and found it to be very useful- actually brilliant!

1.   Open your image in camera raw (you can do this also with Jpegs and Tiffs!) and make all the usual adjustments
2.   Hold the shift key and click “open” to open the image in Photoshop as a smart object
3.   Duplicate the smart object layer in Photoshop by> Layer > Smart Object> New Smart Object via copy (You can not just drag the layer down
     to the bottom of the layer palette to duplicate it- this does not work for the next step!)
4.   Double click the duplicated smart object layer and camera raw will open this layer once again
5.   Move the clarity slider to at least -40 or more and watch what happens to the skin(!)
6.   Once happy with the skin in raw just click “O.K.” and you are back in Photoshop
7.   Layer > Layer Mask > Hide All => this will hide the effect of the smooth skin completely
8.   Choose the brush tool and make sure it is a soft brush. Set the foreground colour to white
9.   Start brushing on the face (make sure you have the black mask on the layer selected- just click it!).
10.  Play around with the opacity of the brush. Once finished: play around with the opacity of the layer if the effect is too strong.

Hope it works for you!

Happy photoshopping!
Stef.

BTW before I forget: you can do the above steps also for eyes/teeth/landscapes... this time just change the sliders in ACR that give you the result you want and then paint the effect into your image in Photoshop. But the one slider that Photoshop's raw converter has that is difficult to replicate is the clarity slider. So try this one first. For eyes: just move the clarity slider up!

Stacking Images or Increasing depth of field

Most of you know that particularly in macro shooting there is the problem that even with a small aperture such as f11/ f13... you still can't get the whole subject in focus. There is a new way in Photoshop CS4 that allows you to combine various images stacked on top of each other as layers- each with a different focus point-and then to automatically erase the out of focus parts of your image. There is also a way to do that in not the newest versions of Photoshop but any other version and in fact also in Elements.

Now before we begin with the darkroom technique - to get this successfully done you need to do the following during the shooting process:

(a) camera must be on a tripod
(b) subject should not move at all during the shooting process
(c) aperture must be kept the same
(d) ideally you work with studio lights/flashes- at least make sure the lighting does not change too much
(e) now the only thing you have to change is the focus ring on your lens. This means switch to manually focussing and start with your first image to focus on a point nearest to you. Your next picture should focus on a point slightly behind the first one and so one. Try not to shoot more than about 5 images or there is a chance that your computer will get hick ups later on... ;)

Let's assume you have done all of the above
Now here ae various ways of doing the stacking- but let's do it the way I usually do it?
(a) open all of your shots at the same time in camera raw and make sure "select all" is ticked once the RAW converter opens up
(b) set the same wb balance for all of them and correct the exposure if needed
(c) don't do too many adjustments in RAW as they can be done later on. So leave stuff like sharpening/ noise reduction and so on for now- don't do that in the RAW converter
(d) once you are done in the RAW converter do not tick open but instead just "done" -> this will close the RAW converter and the images are adjusted in Bridge or Lightroom.

Next step and this differes depending on the version of PS you have- let's go with the newest version of PS
(a) ctrl click all the images in Bridge that you want in your stack > click tools at the top of your screen > Photoshop > Load files into Photoshop layers
(b) now after opening but before you do anything else you might want to change you image mode to 8 bit files depending on how powerful your computer is! Do the following if you want to do that: Image > Mode > 8 bit. Then click the bottom layer in your layers palette- hold the shift key and click the topest layer in your palette- now all of your layer should be selected and "blue"
(c) edit > auto-align layers > click auto
(d) edit > auto-blend layers > tick "stack images" > now here it gets tricky- very much depends on the power of your computer...

If you at this time have a problem that either your program shuts down or anything else- here is a work around:

1. make sure you work with 8 bit files
2. make sure you don't take too many files at once: you can first stack the first two images of your shooting; then stack no 3/4 and 5 and lastly stack the two combined images that you should have flattened and saved by then

Now back to the last step...
(a)Let's assume your computer is still smiling and happy than you should have a bunch of files on top of each other- each with a layer maks created automatically by the program. Check at 100% image size the details of your image. There should be no problem if you did what I have written at the very top...if there is... than click and unclick one by one the eyes next to your layers and check whether this improves the quality. In worst case scenario you have to manually "repair" the mask of that layer or even just delete this one layer.

(b) once you are happy with it- flatten the layers (your file size will be huge at that time!) and save this copy (!)
(c) then and only then adjust your image as usual- preferably in LAB mode- not sure I have discussed this before- if not will come back to that at a later stage.

Now for all Elements users or former CS versions
(a) basically what you need to do is to copy and then paste the images on by one into the first one of you series. You do this by: select > all > edit > copy > click on your first image > edit > paste
(b) no add a mask to each of the layers but the background layer: layer >  layer mask > reveal all
(c) now choose a soft brush and black as colour and paint on the mask to hide the blurry parts of that layer. Once done you can flatten the image and save it.

Anyhow this all sounds much more complicated than it is as long as during the shooting of the image you don't move your tripod or change the position of the subject... then it gets tricky...

Hope this helps- look here for an example:

How to avoid unnecessary noise reduction- or how to apply noise reduction partially

Now I guess you all know that any kind of noise reduction leads to a softer image? I guess you also know that most of noise problems due to high ISO or long shutter speeds occur in the darker/shadow parts of your image.

One way of dealing with avoiding noise reduction and therefore softness in highlights or other parts of the image that do not need noise reduction is by applying it to a duplicated background layer and then erasing parts of the noise reduction on this layer- either with the help of masks or simply by using the eraser tool. The other day I discovered a very neat method to do this much quicker. Imagine an image where you have quite a lot of white houses within a lot of darker trees. To erase (on the noise reduced layer) all those white house so that there is no noise reduction in the highlights takes an enormous amount of time!

Now here is a way of doing this much quicker:

1) Duplicate your background layer
2) Do all your noise reduction on this layer with whatever method you like and apply a mask (Layer > Layer Mask > Reveal All or just click the mask button at the bottom of your layers' palette)
3) Select > Colour Range > click the little triangle at the top and choose highlights
4) Feather this selection by Select> Modify > Feather > Choose sth like 2/3 pixels- not too much you got to play around with this depending on your image
5) Click on your mask > Edit > Fill > Choose black

This should already help a lot.
BUT: you can do even better by doing the same steps as above but this time choose midtones and instad filling it with black fill it with mid grey and this will reduce the noise reduction not completely but exactly 50%.

Finish the image off by the edge sharpening method which can be found somewhere else in these tips ;)

I hope this helps?

Sampling Colors

This is a very brief but neat one:

Did you know that you can sample colour with the colour picker from anywhere and anything on your screen- even if it is outside of your document or PS? Just choose your colour sampler tool or in other words eyedropper tool- click first somewhere on your image- then (keep the mouse button pressed) just move the cursor outside of your document and release the mouse button over the colour you want to sample.

Good one- ey?

Here's one I found in an issue of Popular Photography to add some blue to the sky.

1 Duplicate the Background Layer

2 Go to Select > Color Range and with the dropper click on your not so blue sky.
Slide th Fuzziness Slider until the preview show enough is selected. Click OK.

3 Click the Add Vector Mask button to add a mask.
Then click the layer's thumbnail to select it instead of the mask.

4 Go to Image > Adjustments > Photo Filter.
Pick Cooling Filter (82) and add as much Density as you desire.

Adding see through Copyright information to your photo.

  1} Open your image or images.
  2} Choose the custom shape tool.
  3} Go to the Options bar at the top and choose the Copyright symbol from the Shape tool and select 'Fill pixels' on the third  icon from the left.
  4} Create a new blank layer and ensure your foreground colour is black (hit d).
  5} Drag your copyright over your photo making sure it is round and leave room for your name, date etc.
  6} Go to Filter menu > Stylise > Emboss. Use the Defaults of 135o, 3 pixels and 100% and hit OK. (You can play with different settings for larger Copyrights).
  7} Highlight your new layer 1 (step 4) and change from 'Normal' to 'Hard Light'.
  8} Pick the Type Tool and position it next to your Copyright symbol and type your year and name or whatever.(Size font as required).
  9} Highlight your Type layer, right click on it and choose 'Rasterize Type'. Repeat step 6 and step 7 also.
10} You can play with the opacity of both these layers until you feel it looks correct. Now go to Menu Layer > Flatten Image.

We now have a see through Copyright. You could make an action of this procedure and apply it to all your photos or make it into a brush and stamp it onto photos you choose.

Making a see through Copyright Brush stamp.

This is essentially the same as the above but is a brush that you can resize, make into any colour and change the opacity as desired then stamp it onto your photograph. It will remain in your brush collection for use when needed. You could also automate it and batch stamp any number of photos.

  1} Go to file > New and insert 800 into width and 200 into height, making sure you change inches to pixels. Change 'Background Contents' to Transparent. Click OK. This is your new canvas to work on.
  2} Choose the custom shape tool.
  3} Go to the Options bar at the top and choose the Copyright symbol from the Shape tool and select 'Fill pixels' on the third  icon from the left.
  4} Create a new blank layer and ensure your foreground colour is black (hit d).
  5} Drag your copyright over your canvas making sure it is round and leave room for your name, date etc.
  6} Go to Filter menu > Stylise > Emboss. Use the Defaults of 135o, 5 pixels and 100% and hit OK.
  7} Highlight your new layer by clicking it and change from 'Normal' to 'Hard Light' and click lock:  'transparent pixels'. Smooth the edges by going to Menu Filter > Blur > Gaussian Blur and insert 3 into 'Radius' and click OK.
  8} Pick the Type Tool and position it next to your Copyright symbol and type your year and name or whatever. (Size font to match the copyright symbol as required).
  9} Highlight your Type layer (which appears when you pick the type tool), right click on it and choose 'Rasterize Type'.
10} Repeat step 6 and step 7.
11} Delete layer 1 in the layer palette by dragging it to the garbage can at the bottom.
12} Choose the Rectangular Marque Tool (2nd icon in the tools menu) and drag it around your copyright, selecting only the copyright and the accompanying words. Go to Menu Edit > Define Brush Preset.  Give your brush a name that you will remember. Click OK.
13} Your brush will now be the last one in the brush menu.

Delete your new canvas and load a photo of any size. We will now stamp your photo with your copyright.

 1} Open a new layer in your photo.
 2} Pick the brush tool and go to the brush: picker at the top, second icon from the left and pick your copyright brush. Resize it to suit and if your photo is dark change your foreground to white (or any colour you like).
 3} Click your brush on the photo to stamp your copyright. Adjust the opacity in your layer palette to make it transparent.
 4} Go to Menu > Layer > Flatten image. Finished.

Removing Noise


For noise or also for uneven skin (pimpels i.e or wrinkles) or if you want to defocus parts of the image the following is pretty much unbeatable:
1. Open up your image in RAW make all the usual adjustments
2. Hold the shift key and then click "open image" -> this will open the image in PS as an object
3. in Photoshop: layer > smart objects > new smart object via copy => you will have now tow layers above each other with a little symbol in the right hand corner
4. Double click the top layer => this will open the former adjusted RAW file once more in ACR (this is the very neat part!!!)
5. in ACR leave everything as it was but do the following: drage the clarity slider to minus around 50 (You need to try this out: look at the image at 100% and see what it does to the noise/ wrinkles. You can overdo this- we will adjust it in a minute in PS) You can also paly around with the noise slider but I have seen the the clarity slider alone does already wonders!
6. Once done with clarity and noise sliders just click O.K. => you will be back in Photoshop and the image will be very soft - no panic!
7. Layer > layer mask > hide all (now it looks like before)
8. The last step depends on you ;) : either a) take a brush with foreground colour set to white and paint over the offending parts of the image; or b) (this is a very neat one...): select > colour range > where it says "sampled colours" click shadows > then select > modify > feather > choose something around 4 pixels > make sure you click the black mask > edit> fill> white; or whatever else methods you want to use to select the offending parts of the image. The idea is to fill the mask with white where the noise is to reveal the adjustments you havedonein ACR.
9. At the end play around with the opacity slider of the layer to reduce the effect to an extent that makes the image believable.

If you don't have the ACR version that includes the facility to open up a file as a smart object there are ways around even if you have an older version: you just need to do more than one conversion of the same file and then combine them in PS (once you open the file in PS- save it immediately under another name- go back to Bridge and open up the same raw file once more in ACR). As you obviously have no clarity slider in older versions it nevertheless works in a similar way by using the noise slider- in combination with reduction of contrast and increasing of the black slider.

Hope this helps? Would love to know from some of you whether you are actually trying some of my methods out and how the success was. Lately I have not put much under darkroom techniques as I am not sure whether you are actually really interested in that stuff. The above method was already under darkroom techniques- under beauty treatment. If you look into the darkrrom techniques: there are other tutorials regarding noise that might be helpful? You have got to try what works best for your particular image! As a rule of thumb I try at least one new technique in ACR/Photoshop every day...
All the best and happy photoshopping!

Toning the “Correct” Way:

O.K. I have not added a new tip in a long time and thought it is high time to do so. I suspect that most of you just use the hue/saturation adjustment layer set to colorize when you want to tone your image let's say to sepia? Hehe- that's not how it should be done. In the traditional darkroom (and yep I am that old...) toning usually only affected the midtones. So the hue/saturation is not the best way to go as it will tone your whole image regardless of highlights and shadows.

Here is what you should do:
(a) Open you image and convert it to b+w
(b) Make sure the colour space is RGB: image > mode > RGB
(c) Create a "colour balance" adjustment layer: layer > new adjustment layer > colour balance
(d) set the blending mode of this layer to “colour”: in the layers palette where it says “normal” > scroll down and set it to “colour”

Now as already mentioned above: in the traditional darkroom the toning process usually only affect the midtones. So make sure that your click under “tone” > “midtone”. Now it is up to you to experiment with the sliders until you get the toning that you like.

Important: If you want to duotone your image than leave the midtones alone and click first “shadows” > choose a colour and then afterwards: “highlights” > choose another colour

If you want you can lower the opacity of the colour balance layer to soften the effect.

On a general note: Don’t overdo the toning- keep it real!

All the best and happy photoshopping!

Stef. :P

P.S. Have just seen: this thread has over 30000 hits so it must be worth it ;)

Sharpening- particularly for out of focus eyes

I came across this tip the other day and must say it does work quite well particularly in cases where in portraits the eyes are slightly out of focus.

1. Make a copy of the background layer
2. Filter- sharpen - unsharp mask: amount 500% (!); radius 1 > click O.K.
3. Filter - other - high pass: radius 20
4. Set the layer from normal blending to overlay and the opacity to 50%
5. Layer- add layer mask - hide all => this will hide the whole effect
6. Set the foreground colour to white and paint just around the iris of the eye to make them sparkle. You can paint over all the other parts as well that you want to make sharper. Be careful not to overdo it and play around with the opacity of the brush when painting with white.

Hope it helps?

Happy photoshopping :P

Making selections using channels

This just came up in another thread and I thought it might be useful for everybody here ;)

I assume that you came across the problem of making a selection before? Quite often the foreground object is too similar in colours to the background to i.e. use the magic wand tool? Or have you ever tried to select a person's hair...

Here is what you can do to make your life easier:

1. Open your image in Photoshop -> in the layers palette -> click on channels -> then click on each individual channel to see where the object differentiates most from the background- in other words where the contrast is the highest between subject and background.
2. Duplicate this particular channel by dragging it down to the little duplicate sign at the bottom of your channels palette
3. Now increase the contrast by going into image - adjustments - levels or curves ( do NOT use an adjustment layer) and really increase the contrast so that you end up pretty much with solid blacks and whites
4. Now make your selection by using the magic wand -> click i.e. on the background
5. Next: drag the duplicated channels layer to the rubbish bin as you will not need it anymore
6. Click on RGB in the channels palette and go back to your layers

You should now end up with a much cleaner selection than you would have if you had chosen the background layer to begin with?

Hope this helps?

Happy photoshopping :P

Increase contrast - the easy way

This is a very easy way to boost contrast in an image and always worth a try:

1. Open your image in PS
2. Duplicate your background layer
3. Click: image > adjustments > desaturate
4. Set the blending mode of this layer to soft light and play around with the opacity.

Happy photoshopping :P

Stef,

Thanks for publishing your alternative sharpening method. I'm very pleased with the way it works and found it's better than previous methods I've used. I can see me using it a lot in the future - so I've created an action :)

Skin retouching

I came across this tip yesterday in the "Photoshop User" magazine and thought it's worth sharing:

1.   Duplicate the background layer
2.   Image > adjustment > invert > change the layer blending mode to vivid light (don’t panic here...)
3.   Filter > convert for smart filters
4.   Filter > other > high pass (on an inverted layer it works in the opposite way: it actually softens instead of sharpens that layer) Use somewhere between 5 and 15%. Make sure your settings are not too high to create halos!
5.   Filter > blur > Gaussian blur: use approx half of the value you have used for the high pass filter (here again: on an inverted layer these filters do exactly the opposite from what you expect them to do)
6.   Layer > layer mask > hide all: now choose a soft brush with the foreground colour set to white and brush over the parts of the image that you want retouched.

If the effects are too strong you can always play around with the opacity of the layer or even the individual filters.

Happy photoshopping!

Colour Boost:

O.K. you have not heard from me in this thread for a while now and I thought I am going to share a nice little colour boost tip with you. It works wonders and I am sure you will like it.

(1)   open up your image
(2)   choose the colour balance tool adjustment layer
(3)   For the first step make sure “preserve luminosity” is checked: choose “midtones”; add a bit of warmth by dragging the blue slider towards the yellow (taking out blue) and the green slider towards magenta (taking out green) Something around -10 for both green and blue is good to start with.
(4)   Create a second (!) colour balance tool adjustment layer. This time unclick “preserve luminosity”. Choose “highlights” and put under red/ green/blue something in the area of +30. Make sure the number is the same in all three boxes (!). This will reintroduce lost light.
(5)   Should the colours be washed out slightly than choose “shadows” with preserve luminosity checked and put something around -10 in all three boxes.

This will boost the colour and light in your image.

Happy photoshopping!

Improve Edge Sharpness

O.K. here we go again after a very long time of silence...

One way of improving edge sharpness/ contrast is by doing the following either in Elements or CS:

1. Duplicate you background layer
2. either: image > adjustments > desaturate or in Elements: enhance > adjust color > remove color
3. Duplicate the duplicated layer once again
4. Invert this layer by clicking : ctrl + I (or image > adjustment > invert)
5. Set the top layer's blending mode to "overlay"
6. Filter > blur > gaussian blur; set the amount to around 10%
7. Merge the top two layers and reduce the opacity.

Hope this is useful?

Stef. :P

Contrast/ Levels/ Curves

Works with all versions of Photoshop and Elements!

This is a new tip and an absolutely fantastic one - one that I use now exclusively!

Instead of using curves/ levels or brightness and contrast directly on your background layer, do the following:

1. Open up your image in PS
2. Make a copy of your background layer
3. Convert this copy to b+w. (There are numerous ways of doing it. Just have a search here in the Photoshop tips. I personally use Silver Efex Pro 2.
4. Dodge/burn/make level adjustments/ curves... on this black and white layer, until you are happy with your b+w version
5. Once done, set the blending mode to "luminosity" and change the layer opacity to your liking.

Voila done! What's good about it? You do not introduce colour shifts and you have two versions of your image: the colour one and the b+w one. (I am aware that you could use i.e. a level adjustment layer and then set its blending mode to luminosity, but I believe this method is more fun and faster)

Happy photoshopping!

How to get rid of Noise in post- production


Let us assume you have shot a picture that is outstanding but that unfortunately suffers from noise due to high ISO settings...

Here is what you can do to rescue it:

a) First of all, open up the image that suffers from noise and note down ALL the settings that you have used to accomplish this shot. This includes raw or jpeg; white balance; shutter speed; ISO; aperture; shooting modes; and so on. In fact you have to note down EVERYTHING that the camera was set at when you shot the original picture.

b) Now, put all the above settings into your camera (you have to set it to M mode!). Next, put the lens cap ON (yes...on) and shoot a black image with the same settings as your original image

c) Now this is important...if you do ANY adjustments in your raw converter to the original image then you have to do exactly the same adjustments to the black image! Easiest is to open up both at the same time in your raw converter and sync the settings for both images. Keep in mind though...it would be better to adjust anything, particularly any exposure settings at the end of the following points!

d) Now load BOTH images as layers in Photoshop on top of each other. Make sure the top layer of the two layers is the black image. Set the blending mode of this top layer to “subtraction” and magically the noise should be gone!

The beauty of this is that you can shoot the black image at a later stage at home. In fact the above method is what your camera does when you set it to NR “on” for high ISO shots.

Happy photoshopping! :P

Here`s a good one that helps precisely to find the mid tone point when color correcting a photo.
Open your photo in Photoshop.In the adjustment panel on the left open a new empty layer.Go to Edit>Fill,then select 50% gray from the drop down menu.Change the blending mode of this layer to Difference.Your photo will look weird but it`s only temporary.In the adjustment panel click on a new duplicate layer and select Threshold.On the histogram move the left slider all the way left.the screen will go white.Now slowly drag the slider to the right,and the first tone to appear is the mid tone point.Select the color sampler tool and click with it on the mid tone point you`ve just found.This will aid you to find it in the next step.You can now drag both layers to the dust bin button to remove them.They`ve done theirjob.In the adjustment panel select Curves,then click the mid tone eye dropper and click it right on the mid tone point you`ve just found.Your photo should now be color corrected.
It doesn`t work every time.Some photos don`t have a mid tone point.In this case you can either leave it alone or guess!


Cheers
