The image of a beautiful woman has been making the rounds in the social network sites. The most noticeable feature of this image is that it is a photographic negative.
Viewers are asked to stare at the red star on the woman’s nose for 30 seconds and then look at away. You could also close your eyes.
After staring at the image for a period of time, the negative is temporarily “burned” onto your retinas. When you look at a light surface or close your eyes, you can see a color image of the woman for several seconds. This is known as an afterimage.
