As for the world of fashion and celebrity, I have the usual interest in the human comedy, but the problems of depiction absorb me more.

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.

But the moment you use an ordinary camera, you are not seeing the picture, remember, meaning, you had to remember what you've taken. Now you could see it of course, with a digital thing, but remember in 1982 you couldn't.

Smoking calms me down. It's enjoyable. I don't want politicians deciding what is exciting in my life.

I avoid the public because the English public is too aggressive these days for me.

In fact, most artists want to make things a bit more difficult for themselves as they go along, to challenge themselves.

Drawing is rather like playing chess: your mind races ahead of the moves that you eventually make.
