Edge of the World
Ever since we have had cellphones, we have managed to create many different optical illusions just through the use of our cameras. Even camera filters have the ability to make you question everything you ever thought about beauty standards.
This photo for example was taken using the panoramic filter on a cellphone camera. We have to admit, when we first saw it we were also very, very confused about what was happening. But then it became clear after inspecting a little further that this is the result of panorama done badly.
