I'm not interested in doing the same kind of picture over and over again. I pose problems for myself. Sometimes they are aesthetic problems and sometimes they are logistical problems.

I realize that as I get more experience as I get older, my perception changes and that feeds the photograph.

The danger is that you can wind up doing tourist pictures. I want to see it fresh and see the little bits of everyday life that a native might take for granted, but that are special to the place, while at the same time, not taking a picture that would be a tourist cliché.

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.

Photography is inherently an analytic discipline. Where a painter starts with a blank canvas and builds a picture, a photographer starts with the messiness of the world and selects a picture. A photographer standing before houses and streets and people and trees and artifacts of a culture imposes an order on the scene - simplifies the jumble by giving it structure. He or she imposes this order by choosing a vantage point, choosing a frame, choosing a moment of exposure, and by selecting a plane of focus.

If I only try to solve the problems I set for myself, then I'm limited by what I can conceive of. I can't solve a problem I can't conceive. But if someone else gives me a visual problem, it can be out of the whole realm of my normal practice.

A quote that I like very much comes close to explaining my attitude about taking photographs. ‘Chinese poetry rarely trespasses beyond the bounds of actuality the great Chinese poets accept the world exactly as they find it in all its terms and with profound simplicity they seldom talk about one thing in terms of another; but are able enough and sure enough as artists to make the ultimately exact terms become the beautiful terms.’
