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.

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.

When you look at pornography, the women become objects, whereas what I'm trying to do is make the person in the photograph as important as their body. And obviously, I like tits and arse, because I just do. I like the sex of taking photographs.

When I worked on an erotic shoot... I shot digitally. It helped the models get into it because they could come over and see what was happening. It was the closest to being sexual, because it was a participatory experience.

If you surround yourself with talented people and you give them the freedom to achieve, then the work will never fail.

I think if you don't love people and aren't fascinated by them, you'll never succeed as a portrait photographer, because your pictures will look cold.

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