In one gallery they actually had a notice which said No Sketching. How obnoxious! I said, How do you think these things got on the walls if there was no sketching?

I do do a lot of talking, because it saves me listening.

I was always interested in photography because it makes a picture.

It's time to debate images, especially when someone's going to prison for downloading them.

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.

There's no need to believe what an artist says. Believe what he does; that's what counts.
