I was amazed by this person who, even though she had everything, would go to feed the homeless and visit sick children and Aids victims. It was like a fairy tale. Who was she really? Why did she do this? She was trying to find love. I wanted the world to see her kindness, her humility: I think she realised that would be her way.

As photographers, we have to find our own identity, our own voice, our own vocabulary. And my question all the time is whether this vocabulary is limited, like our own vocabulary that goes from A to Zed, or whether this vocabulary can carry on growing. And to me, I hope that it carries on growing.

Some things happen by accident - embrace them.

My favourite words are possibilities, opportunities and curiosity.

There is something about Prince William and Prince Harry that brings real modernity to the British royal family. They are also very open, human, and kind, and this is what I have tried to capture in the pictures I have taken of them as well as in my pictures of Prince William and Catherine.

Most photographers go and photograph something that they see, that exists, and that somebody else has created - they document it. But fashion photographers have to create what they're going to photograph. We have to go into the thought and build it up, get a girl, get a guy, get a situation, get the house, get the decor. It's the meaning of the word photography: "writing with light."

I had the right amount of detachment to go back and really appreciate what I had grown up with. There’s a particular style that is very Peru that you don’t see anywhere else; it’s got so many different imprints. When you mix Incan minimalism with the heavy, ornate Spanish Baroque, it is very interesting.
