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?

Happy photoshopping!

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!

Happy photoshopping

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?

Happy photoshopping!

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!
Stef.:P

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!
Stef. :P

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.

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.

In reply to AScots request, (I feel a bit funny posting here, I  hardly feel qualified but here goes) Open Adobe bridge, select the image or images you want to resize then in tools select photoshop then image processor, photoshop will then open and the image processor box will open to, you can then select where to save the images,  file type (jpeg PSD or tiff) the quality level and the size in pixels be careful to untick the run action box in preferences (mine was ticked by default) hope this helps.

PS the reason I go thru bridge is because that was how I was shown and apparently the "image processor" opened through CS3 only allows you to open folders not single images

Thanks Mark - and Ascot - for coming up with this tip. It's another option I now have for resizing batches of photos - see the thread on MS Image resizer and PS7/CS3... Many thanks :)
