The idea that the snapshot would be thought of as a cult or movement is very tiresome to me and, I’m sure, confusing to others. It’s a swell word I've always liked. It probably came about because it describes a basic fact of photography. In a snap, or small portion of time, all that the camera can consume in breadth and bite and light is rendered in astonishing detail: all the leaves on a tree, as well as the tree itself and all its surroundings.
