I started being a photographer because I liked fashion. I liked the idea of dressing up and changing my look. I got earrings, dyed my hair. I would dress like a fashion photo.

I don't like a tormented photograph. Something attracts you in them, but the attraction isn't because she has a pot on her head or tonnes of make-up and weird clothes and weird everything.

My original idea was to photograph Princess Diana in her tiara. But then I thought, am I interested in seeing another picture of her as a royal person, or would I rather see what she is actually about? And that's why I decided to do her without jewels, without shoes, without trimmings.

Ultimately, I made my range wider because I wanted to suit each publication that I worked for. Talk about reinvention - I'm like the Madonna of photography.

I think my sense of color I have got from my upbringing in Peru.

I have no real training in the history of fine art or furniture; my eye just works by proportions. I react intuitively. In London, it's all about color because the weather is so gray, and in that cold light they look beautiful.
