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!
Stef. :P

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
