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

I see the iPad as a wonderful new drawing medium, but I am at a loss as to how to make it pay.

I was 18 when I first visited London, I'm very provincial like that, but I must confess the moment I got to America I thought: This is the place. It was more open, with 24-hour cities and pubs and restaurants that didn't close.

What the art historians had forgotten is that in Chinese, Japanese, Persian, and Indian art, they never painted shadows. Why did they paint shadows in European art? Shadows are because of optics. Optics need shadows and strong light. Strong light makes the deepest shadows. It took me a few years to realize fully that the art historians didn't grasp that. There are a lot of interesting new things, ideas, pictures.

I draw flowers every day and send them to my friends so they get fresh blooms every morning.

The history of photography needs clearing out. It needs something else now. Because photography always acknowledged there were cameras before photography.

I think we seem to remember things in still pictures. I never gave up on painting. When they said painting was dead, I just thought, Well, that's all about photography, and photography's not that interesting, and it's changing anyway.
