Why can't a photograph be all four things at once? -be an art object; be a document, what ever that means exactly, but deal with content; be a formalist exploration; and operate on some, metaphor is not the right word but, resonant level.

I meet young artists and it becomes clear that with some the main motivation is getting a show in Chelsea. It strikes me that this is very different to the way it was for me, which was that I wanted to understand photography and the world and myself.

A work can do many things at once, and it doesn't have to be just about the world, it could also be about photography, it could be about perception, it could be an exploration of the medium. It could be a document, it could be a visual poetry, and it could be a formal exploration all at the same time.

I don't have to have a single point of emphasis in the picture. It can be complex, because it's so detailed that the viewer can take time and read it, and look at something here, and look at something there, and they can pay attention to a lot more.

I know that people think of my work from the '70s as American, but I've been going to other places for a long time.

A lot of the photography I'm doing and thinking about is directed at Instagram.

There's something arbitrary about taking a picture. So I can stand at the edge of a highway and take one step forward and it can be a natural landscape untouched by man and I can take one step back and include a guardrail and change the meaning of the picture radically... I can take a picture of a person at one moment and make them look contemplative and photograph them two seconds later and make them look frivolous.
