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.

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.

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

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.

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.

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.

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.
