...all along I've had an ambivalent relationship to photography - but as to whether I thought it an art form, or a craft, or a technique, well, I've always been taken with Henry Geldzahler's answer to that question when he said, I thought it was a hobby.

We all know a mirror reflects us, if you look in it. If you move, the reflection moves. If you project from a mirror, meaning it will project an image, it's nothing to do with you. The world seen by nobody.

When you stop doing something, it doesn't mean you are rejecting the previous work. That's the mistake; it's not rejecting it, it's saying, 'I have exploited it enough now and I wish to take a look at another corner.'

Picasso is still influencing me. Of course, I haven't got that kind of energy, or skill.

I do believe that painting can change the world.
