Television is becoming a collage - there are so many channels that you move through them making a collage yourself. In that sense, everyone sees something a bit different.

Shadows sometimes people don't see shadows. The Chinese of course never paint them in pictures, oriental art never deals with shadow. But I noticed these shadows and I knew it meant it was sunny.

In fact, I'm a bit of a slob, but I've always said my excuse, I have a higher sense of order, I can see it where others can't. That's my excuse for slobbery, I must admit, but I think it's a good one.

Laugh a lot. It clears the lungs.

I can often tell when drawings are done from photographs, because you can tell what they miss out, what the camera misses out: usually weight and volume - there's a flatness to them.

Movie actors disappear - any young person wouldn't know Cary Grant. They're going to disappear. Fifty years ago, you thought film was here to stay. But nothing is here to stay, actually - except perhaps paintings and drawings.

But slowly I began to use cameras and then think about what it was that was going on. It took me a long time, I mean I actually played with cameras and photography for about 20 years.
