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

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

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

Look at lots of exhibitions and books, and don't get hung up on cameras and technical things. Photography is about images.

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 have always loved reading, so was interested in the literary world, and took many literary portraits.

I've been working with the land for most of my life; walking it and photographing it. And I love it to bits.
