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?

Social media's currency is the single photograph. Whereas, every time I look at a photograph, I look at twenty or thirty photographs. I'm looking for a narrative. And that's a different kind of construct. If you're a poet and you put a line from your poem online, "The trees bending over gracefully," or something, you can get a tick. But that has nothing to do with your longer poem.

My current project was shot on film, and because of that I've spent my entire day removing dust-specks from negatives. You wouldn't have to do that on digital because you don't get dust on the scanner. I say to myself, "Why am I doing this all day?" I could have just bought a digital camera and I wouldn't have to remove dust-specks ever again. But when you move closer to a film image, it has a real truth to it. And I really like that.

I was always interested in drawing and painting. I enrolled in college to study painting. But I didn't have any livelihood when I graduated. My mother died very young, and I didn't have any home, so I had to find a way to earn a living. It seemed to me that photography - to the great disappointment, I have to say, of my painting teacher - could offer that. So I went and did a degree in photography, and then after that I could go out and get paid for work. For portraits, things like that.

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 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.

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.
