I worked in the NHS as a hospital orderly during my national service, and people thought it was a noble service. But over the years it's lost its humanity.

What an artist is trying to do for people is bring them closer to something, because of course art is about sharing. You wouldn't be an artist unless you wanted to share an experience, a thought.

About shadows: do we see shadows? Loads of people don't. A camera will notice a shadow, but how many people have got a shadow in front of them when they take a picture and don't notice it, and then they see it in the photograph because the photograph will catch the shadow.

I think I’m greedy, but I’m not greedy for money - I think that can be a burden - I’m greedy for an exciting life.

The moment you cheat for the sake of beauty, you know you're an artist.

You can't believe any picture nowadays, if it's digital. You can't really believe. If you see me shaking hands with Mr. [Barack] Obama, it doesn't mean I ever met him, does it?

The camera can't see space. It sees surfaces. People see space, which is much more interesting.
