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.

Well, people from the "me" generation use photography to show off what they are doing, to show the world themselves and their friends. Those sort of diarized accounts have always been there. But the phenomena of making those diaries public is new, isn't it?

I think it's terribly important to reach out and understand all the different types of life and the different types of challenges that are present around the world. And I think the more people who can do that the better our planet will probably be.

Photography was increasingly being seen as something outside the art world. As a sort of illustration. They just fired the director of photography at the Sunday Times Magazine - that's where everyone went with their photo essays in the '60s, '70s, and '80s. It was the place to get published. It is an issue. And I feel it. There's no budget. The budget-holders are very often people who've been to the professional colleges where art is not taught. So art as a part of education is something that's missing - since Thatcher's day, anyway.

As humans, we need to question all these notions. What does freedom mean for us? What are our responsibilities? It takes one-250th of a second to take a photograph. So I have the whole of the rest of that second - and of that day - to think.

It's certainly important to include text beside documentary photographs. Furthermore, it's important to include text in a way that's useful and accessible.

There is a danger in our modern practice of using embedded journalism. As there is less and less money available for journalism to uphold its independence, there is a temptation for people to take short cuts. If this army or that army or this corporation is willing to pay for your flight or your accommodation, then it's much more difficult to tell what the real story might be. I do have a concern about that.
