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

...if you think of modern art like sex in all its forms - heterosexual, bisexual, homosexual, multipartnered, bestial, whatever, with absolutely no holds barred and with everything available and permissible - that would be modern art.

I came to photography by accident.

Recording sessions were stimulating to photograph, because everything was in motion: the subject, the musicians, the technicians and the photographer. You needed fast reflexes to keep up with moving targets, and sensitivity and skill to get the pictures while keeping out of the performers' eyeline so as not to break their concentration.

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.

You should never reveal your true age.

What has changed is that when I photographed, most people that I photographed didn't have the right of refusal on their work. It would take a Marilyn Monroe at her height to be able to dictate that.
