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.

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.

Reading is always a way of forming a bond with other people. I'm not very good at socializing - I quite like spending time alone - so reading is a way of engaging quite deeply with the way other people think. Quite often when you meet other people socially you don't get to have a conversation of any depth. You end up talking about how well or how badly someone is doing at school or something of that sort. Questions like, "What we are," "Who we are," "Where are we going," you get those from literature and from people that spend some time thinking.

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

I think, oddly, that the world of the amateur is quite self-contained, and it depends on "likes" from other amateurs to perpetuate itself. Of course an awful lot of my colleagues are involved with Instagram - they get likes and dislikes, maybe just likes, I don't know - but I think that it's far less self-contained, the world I work in. It goes off in different directions, and is dependent on responses different from a tick or a like or whatever.
