What do you hang on the walls of your mind?

I had in mind a long career.

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.

It doesn’t matter if you use a box camera or a Leica, the important thing is what motivates you when you are photographing. What I have tried to do is involve the people I was photographing. To have them realize without saying so, that it was up to them to give me whatever they wanted to give me . . . 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.

...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.

If the chemistry is right between star and photographer and the geometry of the pictures pleases the star, often the two people end up with a long-term professional friendship during which they continue to work together and to produce highly personal images.
