That's one of the wonderful things about the whole process of photography - eye contact can be very revealing.

When I was starting, I was very much influenced by the straight up, eyes to camera style of August Sander. He is really the only one. Had I known then the work of people like Ken Russell, Vivian Maier, Helen Levitt, and Steven Berkoff, they would undoubtedly have influenced me too.

To me, the counterculture was always what I grew up with the hippies in the late '60s. But, however you define it, it's really the excesses of youth and it's something that everyone goes through to some extent. Or if they don't, they should do.

The reason why so many of my photographs in the book were taken in stairwells and corridors was that that was the only bit of spare space available and, in some cases, the only place where there was enough light to see anything. Even then, it was often so dark that I couldn't tell which gender my subject was (not that I particularly cared) and too dark, before the era of autofocus, to focus. I had to find a light (or carry a torch) and pre-focus.

I preferred that option, where my camera (and by proxy, me) could look them straight in the eye. The way they reacted to me was always interesting. Sometimes hard young men would reveal vulnerability and a softer side. In the case of teenage girls, I often got a fascinating glimpse of the woman inside.

Nowadays everyone has a camera and the Internet means everything is instantly accessible. Unlike some photographers, I don't see this as a problem. If anything interesting happens in the world today, there will be someone around to record it.
