"A photograph is just a set of graphics. And I say, for the moment, forget about content, forget about subject matter, we’re just going to talk about photography in a graphic sense. Because when you boil it down, it’s a set of graphics on a piece of paper, or projected on a wall or on a computer screen, whatever. It’s not the world; it’s an abstraction of the world. But people don’t learn that. They think subject matter, subject matter, subject matter, and they never understand."
