Photography to me is an addiction. I get jittery after a couple of days without a camera. Everyone who knows me says I'm happiest when I'm shooting.

My Dad taught me that the English upper class are sent to school to be taught to be confident, whereas in Glasgow you're born confident. I've always thought that pretty much summed me up. Born confident.

At the end of the day, it's only a photograph and if someone is going to get really upset about a photograph, then they have a lot of issues. I just roll with it and see what happens.

I always used to say to my ex-girlfriends that I could never take a good photograph of them, because there was too much of an intimacy between us, but actually the real thing is, if there's a proper intimacy between you... I find it really compelling and exciting - it's quite good foreplay.

You have to believe in what you're doing otherwise what's the point?

There's a time when people say your work is revolutionary, but you have to keep being revolutionary. I can't keep shooting pop stars all my life. You have to keep changing, keep pushing yourself, looking for the new, the unusual.
