Photography for me has been tremendously good, because I'm not a very sociable person. I'm happy reading or sitting in the library or going for walks. So photography has brought me in contact with people and made me understand people in a way that I probably wouldn't have done if I hadn't been a photographer. And so I'm grateful for that, really.

We sort of understand how painkillers work. You take one, and it reduces your headache. We don't understand how photographs work. And that, to me, is an essential problem as a practitioner.

What people that are professionals in the art world - both in literature and the other arts - always try to do is to recognize the feasibility of making the transition from the particular to the general - to make the transition from the portrait of one postman - to take Van Gogh, for example, to something that is every postman. That synecdotal transition that most selfies don't make. But we who live in this world, and not simply in our private realities, understand that that's the transition our art has to make.

The world of photography is very self-aware. Everybody is always looking around. So it's quite difficult to stand up with a megaphone and declare, "This is what I think." As a reasonably shy person, I found it difficult to do that.

I love photographing. I love the experience of being around all the things that surround you when you go out to do work.

We don't understand what photography is doing. We don't understand the power of its rhetoric. We don't understand why the Provoke photographers showed Tokyo city as a ghastly and alien city when it was really going through this period of mega-capitalist growth. It's a very, very, very powerful force, the photograph. People ask me why it has such an ability to captivate us. And I just don't know.

There's an awful lot of work being done that no one ever sees, or that is only seen in the gallery world. I feel that the public are losing touch with the great stuff that's being done in photography.
