Quality doesn't mean deep blacks and whatever tonal range. That's not quality, that's a kind of quality. The pictures of Robert Frank might strike someone as being sloppy-the tone range isn't right and things like that-but they're far superior to the pictures of Ansel Adams with regard to quality, because the quality of Ansel Adams, if I may say so, is essentially the quality of a postcard. But the quality of Robert Frank is a quality that has something to do with what he's doing, what his mind is. It's not balancing out the sky to the sand and so forth. It's got to do with intention.

When I get up in the morning I brush my teeth and go about my business, and if I am going anywhere interesting I take my camera along.

I like to think I keep my mind open. When I walk the streets I don't look for anything in particular. I come from a philosophy that believes you shouldn't have preconceived notions - that you don't need a gimmick. That you should just photograph what you react to - what you see.

I'm almost violent about that stuff - electronic manipulation of pictures. I think it's an abomination. I reject it all. I mean, it's OK for selling corn flakes or automobiles or for taking pimples out of Elizabeth Taylor's face, but it undermines the thing that photography is about, which is about observation and not about manipulation of images.

I'm an amateur photographer, apart from being a professional one, and I think maybe my amateur pictures are the better ones.

If you're not a curious person, you're certainly not going to be a good photographer.

The main thing is to study pictures and stop listening to the pontifictaions of photographers. Photographers aren't oracles of wisdom. If they're good photographers, then take a good look at their pictures - what else do you need?
