Changing Eye color and eye retouching in photoshop.

Before	After

Lets begin :)

---

First, open your photo, and zoom in to its eyes, I chose this one:

Changing Iris Color.

step 1

Make a selection of the iris with any tool you want, I chose to use quick mask.
click on the quick mask icon on the toolbar or press Q to start quick mask mode.


Select the Brush Tool
Choose a brush half as big as the iris, with hardness around 70%
and paint over the iris with black, anything you masked would become transparent red.


Mask the whole iris, if you make a mistake brush over it with white to delete.
click the quick mask icon again or press Q to exit quick mask mode.
You'll get a selection of anything except the masked area
choose any selection tool
Right click on your picture > select inverse
Now you should have a good selection of the iris.
Right click again on your picture > Layer via Copy.
This would create a new layer with only the selected part.

step 2

With the new layer selected, Go to Layer > New adjustment layer > Color Balance.
Check the V in Use Previous layer to create clipping mask
So only the iris area will be colored.



Change the settings to get the color that you wish, I used these:


The color I got looks too bright, So I added another layer to fix it:
Go to Layer > new adjustment layer > Brightness/Contrass
Check the V in Use Previous layer to create clipping mask as before.
Change the settings until you get a good result.
I used these:


This is my result so far:

Whitening the eye to remove veins

step 3

Go back to the Background Layer



Use the quick mask tool again to get a selection of the white part of the eye, Don't worry of you get out of the lines a little, we going to fix it later.
Press Q to start the quick mask mode.
Use some brushes with their color set to black, and mask the whole white area of the eye.


Press Q to exit quick mask mode.
Press Ctrl + Shift + I To select inverse.
choose the Selection Tool
Right click on your picture > Layer Via Copy
Go to Layer > New Adjustment Layer > Hue/Saturation
Check the V in Use Previous layer to create clipping mask
Add a some lightness, and you can also reduce the saturation, don't make it too bright so you won't get a creepy unnatural look.
I used those settings:

step 4

Some parts along the edges might look too white, so we need to erase them.
In the layer window, select the layer with the eye white.


Choose the Eraser Tool
Use a soft brush (hardness set to 0%).
And Opacity at 25%



Stroke a couple times along the adges until you get a good result.
You May also change the layers Opacity if it still seems too white.



This my end result.


next, we're going to add some highlights to the iris.

Adding Highlights to the iris.

step 5

Make a new layer by clicking the create a new layer icon in the layer window or going Layer > New > Layer.


Change the layers blend node to Overlay

Choose the Brush Tool
Select a brush about one third of the iris size,
with its hardness set to 0%.
And Opacity set to 15%

Stroke with white couple times around the iris.



The brush work doesn't have to be even, actually it looks better when some parts are brighter then others.
Here's a picture that shows how I used the white brush (change the blend mode to normal to see this), The upper-right part of the iris is very white, and there is also a reflection on the buttom-left.



Back to Overlay mode,
This is my final result.
