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.

I have a huge respect for the dedication that many people have, on the other side of the Atlantic, to photography. You can count them on one hand here. There's less respect for a Magnum photographer in Britain than there is in America. It's a much more postmodern culture here.

We create these walls between fact and fiction, but often the difference between the two is as little as that between a real name and a pseudonym. So I'm not sure about those walls - certainly not in the realm of visual arts.

After my mother died, I lived with relatives. Reading was a means of escaping into other worlds, as photography, much later, was to become.

There was a time, right up until the end of the Second World War and beyond, when white people in Europe thought that they basically owned the world and that everybody else was a sort of servant, or a curiosity, or whatever. And that informed 99 percent of the photographic practice that was done. Without being able to address that, I felt I would have failed in my attempt to explain what the urge to document is.

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.

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.
