Take a photo of a person and give them zombie eyes!
Instructions:
1. Open a photo of a person in Photoshop that is looking at the camera.

2. Select the Clone Stamp tool.

3. Begin clone stamping the white areas of color around the pupil and retina. Clone stamp over the entire eye, trying your best to keep as little variation in color as possible. It doesn't have to be perfect, because we'll blend it better in the next steps.

4. Now select the Smudge tool. Make sure the Strength is somewhere below 50%.

5. Using the smudge tool, begin pushing in the darker color from the outside into the inside of the eye. So that it leads from color to the white. This will give the eye a rounded effect and look more convincing.

6. Do steps 2 through 5 with the other eye.
7. Choose a dark color the matches the lining of the eye. Select the Paint Brush tool, set the opacity to 30%, then go over the lining of the eye a few times. (Use the smudge tool again on the lining of the eye if necessary so that it isn't too dark and obvious).

8. You're done! You should now have a photo with zombie eyes!

hope you'll enjoy it ......
