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.

Things are very different now because a lot of those little clubs don't exist. In Soho for instance, where nearly half my nightlife photographs were taken, it's rapidly changing. There isn't the same after dark frisson of excitement about the place any more.

My parents, though very loving, were not what one would ever describe as outgoing and therefore when I was young I was quite shy and socially awkward. Having a camera changed all that. It gave me an excuse to go anywhere and approach anybody.

Many nightclubs from this era were very loud and very dark. Plus some of the best ones were incredibly crowded. To begin with, I could seldom get back far enough to get people into frame from head to foot and when I could, people would be constantly walking in front of me all the time. Then I bought a 24-mm lens and only had to be four or five feet away.

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.

I went from being an underpaid ad man to quite a successful photographer in a very short time. Success breeds confidence and as soon as I got properly confident, I developed my own style. After that I never looked back.
