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.

I remember driving around with my parents when I was little and looking out of the window and being very aware that it was the shape of a film screen when you went to the cinema. This was how I first saw the world, framed through a car window.

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

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.

I think the relationship between print and film is symbiotic, it's more about evolving and complimenting your existing content. The two are very much interconnected.

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.
