Some pictures make you look twice, some make you smile, and then there are those rare masterpieces that make you question reality itself. This image falls into the last category. At first glance, you see a herd of black donkeys walking across a sandy, almost desert-like landscape. But then—wait a second—why do their shadows look like zebras? Is it a trick of the light? Some bizarre photoshop magic? No, it’s pure, unfiltered genius—an incredible example of how perspective and nature can create an optical illusion that baffles the mind.
This National Geographic Picture of The Year is one of the most beautiful pictures explaining optical illusion.
