I recently had a talented young man in my photography class and he was using a fish-eye lens on his camera. I try and keep away from "gadgets" and work with just my camera, but the images he created showed me a whole new way of seeing the world and so I decided to add a fish-eye lens to my camera bag. I'm having such fun playing with it. It allows me a whole new perspective on very ordinary things.
Every photograph looks like a small world in itself.
