Have you heard of the afterimage effect?
Its a phenomenon in which continuing to look at a light will cause the lights image to remain visible as an afterimage, after the light itself has disappeared.
One such phenomenon is called the complementary color afterimage. Lets use a somewhat mysterious experiment to try it out...

All you have to do is take a photo with your camera, or select one from your Camera Roll.
After that, all you have to do to run the experiment is keep staring that the photo.
What on earth is going to happen?

The images you create can be saved or shared.
How about sharing this mysterious experiment with your friends?
* Not all photos will work particularly well
