I still love taking pictures with Polaroid film. For me, it offers the most beautiful way of capturing reality and transferring it onto a flat piece of paper.

I would love to photograph Stephen Hawking. I am just fascinated by science, I really am.

This was all very new to me and I did not want to ruin his film! So we worked hard on that basis of confidence that is needed to collaborate comfortably.

It's incredible to have been part of fashion history - my whole career has been one big highlight.

So many times I've wanted to crack up, standing there stiff while seven women are crawling round my toes fixing hems and the designer's having a freak-out because the denim cuffs are crooked. I'm on the verge of hysteria.

I felt like I was in the best photography school in the world - I had Herb Ritts, Bruce Weber, Richard Avedon and Irving Penn teach me.

There are particular images that I like. Allegro is composed of a series of still life photographs that has been put to speed. There is so much care that has gone into the composition of the cinematography.
