A Fish eye camera is said to be like seeing through a fishes eye. But how do we really know what the view from a fishes eye looks like? Are we assuming that because a fish's eye is round and bulges that their view of the world is round and bulging as well?

Well it is actually just a wide-angle lens that takes in an extremely wide, hemispherical image. An interesting fact is that it was originally developed for meteorology and to study cloud formations. But after this it became popular in the world of photography because of the unique distortion in the frame.

I had no idea the fun Fish eye lens had origins in the study of the atmosphere. I guess you really do learn something new everyday.
