Beyonce’s makes one hell of an optical illusion! What I want you to do (once again) is to stare at this negative photo of her for a minute or so. Don’t forget to fixate the dots on her nose while you’re doing it. After some time, turn your eyes to a plain surface right next to the image (a ceiling or a blank wall would serve fine as well). A “negative of a negative“, a proper image in full-color if you will, will then appear momentarily. The more you blink, the better afterimage effect you’ll experience! If this version wasn’t enough, you may try the full size version located here.
