It sometimes takes a foreigner to come and see a place and paint it. I remember someone saying they had never really noticed the palm trees here unti… - David Hockney

With chemical film, it was possible to alter photographs, but you had to be an expert. That's not true any more. The LA Times fired a photographer at the beginning of the Iraq War for editing two shots together. Photography is crumbling. Certainly it is for the newspapers a bit now, isn't it? There will be painting again, absolutely!

When conventions are old, there's quite a good reason, it's not arbitrary. So Picasso discovered that, as it were, and I'm sure that for him that was probably almost as exciting as discovering Cubism, rediscovering conventions of ordinary appearance, one-point perspective or something. The purists think you're going backwards, but I know you'd go forward. Future art that is based on appearances won't look like the art that's gone before. Even revivals of a period are not the same. The Renaissance is not the same as ancient Greece; the Gothic revival is not the same as Gothic. It might look like that at first, but you can tell it's not. The way we see things is constantly changing. At the moment the way we see things has been left a lot to the camera. That shouldn't necessarily be.

I've started painting much more freely, and faster. I think it's working in the theatre that did it. You know what the Glyndebourne scene-painters said about my The Magic Flute? They said they had to wear sunglasses to paint it.
