I think if I ever get satisfied, I’ll have to stop. It’s the frustration that drives you.

I came to photography by accident.

I realise that I had the best of serious picture journalism. There was an innocence in our approach, especially in the 1950s and 1960s when we naively believed that by holding a mirror up to the world we could help - no matter how little - to make people aware of the human condition.

If the photographer is interested in the people in front of his lens, and if he is compassionate, it's already a lot. The instrument is not the camera but the photographer.

What I have tried to do is involve the people I was photographing... if they were willing to give, I was willing to photograph.

I had in mind a long career.

What you need to be a good photographer is an overwhelming curiosity and a good digestion.
