Once I became a photographer, it stopped me being scared or intimidated by gangs of young men of whatever stripe. Initially, I could hide behind my camera but eventually I came to realize that if I was polite and friendly to them, then they probably would be to me too - a good life lesson.

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

Only a very small proportion of us take those excesses with us into later life. In the age before everyone had a camera, it was worthwhile, in my opinion, to record those excesses. Sometimes, many times actually, the young people I photographed were only dressed that way for one night; that one night that they got snapped by me.

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.

In the age of social media, you have the selfie and some people - not always young people - seem obsessed with showing the world what their face looks like almost every day. Just like some people are obsessed with showing the world what their dinner looks like. It's beyond my understanding to be honest.

It's more about subtracting every single buck from the tourists that still flock there. Gentrification and the need for developers to maximize their profits from every square inch of the place means that there just aren't any scruffy little basement clubs left. Those scruffy little basement clubs were the areas lifeblood. Now, it's all penthouse flats and global brands. They destroyed the very thing that drew people there in the first place - it's superficial sleaziness.

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.
