It's a difficult thing. I try not to make a simplistic argument that the 'making' happens in the darkroom, but that it's more a state of mind while actually out with a camera. A thoughtful process of gazing and constructing the image. If you're a street photographer of course, it's not so much the 'making' as a purity of seeing and intuition - we're quicker to label this kind of approach 'genius' I think. Bresson is the genius, whereas Ansel is perhaps more of a grafter in people's eyes, then somebody like Harry Callahan is somewhere in between - the perfect photographer in my mind for that reason. He seemed to occupy dead center and avoided any kind of genre stamp, maybe because he did everything!
