You can't make a great musician or a great photographer if the magic isn't there.

You should never reveal your true age.

Themes recur again and again in my work.

I look for a sense of reality with everything I did. I didn't work in a studio, I didn't light anything. I found a way of working which pleased me because I didn't have to frighten people with heavy equipment. It was that little black box and me and £5 worth of film in my pocket or maybe it was only £2 in those days.

I have been poor and I wanted to document poverty; I had lost a child and I was obsessed with birth; I was interested in politics and I wanted to know how it affected our lives; I am a woman and I wanted to know about women.

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.

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