What drove me and kept me going over the decades? If I had to use a single word, it would be 'curiosity.

...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.

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.

I had in mind a long career.

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 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.

I came to photography by accident.
