The way men are seen in photography, in fashion, and the way that men look at pictures of themselves has changed in recent years. It is a subject that has come into focus: The masculine image, a man's personal style, changing attitudes to the male face and body.

Ive been criticised for pretty, smiley photographs, but at least someone is happy! In my mind, I am always giving the image to the sitter.

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.

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.

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.

My favourite words are possibilities, opportunities and curiosity. I think if you are curious, you create opportunities, and then if you open the doors, you create possibilities.

The more I photograph women, the less it is about transformation. Women are beautiful. All that really matters is enhancing that.
