This video guides you through a process you can use in Adobe Photoshop CS3 or CS4 in order to change a persons eye color. The computer user shows how to first select only the iris of the eye by guiding you through which tool bar buttons to use. You should then zoom in close to the eye in order to very accurately select just the iris. Once the iris is selected you will go to the select menu then click "New Fill Layer" then "Solid Color..." When the dialogue opens up you will change the Mode to "Soft Light," name the layer "Eye Color," then select the desired color. After you are finished adjusting the eye color don't forget to save your new image.
