The viewer must bring their own view to a photograph.

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

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.

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

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

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