Change eye colour in Photoshop CS4

The process of changing the eye colour in Photoshop is actually a pretty simple one, requiring only a good mouse (it's hard to do this with a touchpad) for the selection of the iris.

Step one: open a person's photo in Photoshop (a picture taken with a high megapixel number is preferable). I'll open the one below


Now, zoom in (Ctrl and +, and press Alt while click&dragging to center the eyes) on the eyes and press Q to enter in Quick Mask Mode. Select the Brush Tool (hardness 100 and pick a lower size, like 13-15).

Start painting over the eyes. Notice that you will paint with red colour. Don't worry, we're just making a selection (the eyes won't turn red). If you want to erase a part of the selection, press X and paint over that part. Press X again to return to normal mode. Keys [ and ] are used to decrease/increase brush size.


When finished, press Q again to exit Quick Mask Mode, then hit Ctrl+Shift+I to revert the selection (to select only the eyes). Copy the selection (Ctrl+C), then create another layer and Paste (Ctrl+V). You should get something like this (background is not visible):


Select the layer containing the eyes (make sure the background is visible) and go to Image - Adjustments - Hue&Saturation. Play with the sliders until you get the desired colour. Once you do that, play with the Opacity slider of this layer (i've reduced it to about 75%)


If you finished, hit Ctrl+Shift+E to Merge Layers, than save your work.
