I'm not faithful to one particular medium, and it's what I try to teach to people who work with me.

I like photographs which leave something to the imagination.

I have always been a very keen walker, though, and I often took a camera with me on my walks.

Born Berlin 1931, Germany, father a British diplomat, mother an American artist. Educated at various schools all over the world. 1958 Settled down to live in London. 1966 Became interested in photography through photographing my young children. No formal training.

I had been working in colour for ten years or so and looked at digital and liked the possibilities it gave me.

You can't expect to take a definitive image in half an hour. It takes days, often years.

I hardly teach. It's more like a gathering of minds looking at one subject and learning from each other. I enjoy the process.
