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.

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.

In Los Angeles, individuality is very big, because people live in secluded bubbles. People don't walk around. They're very insular, and that allows for people to be whatever they want.

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.
