I've been a documentary photographer for much longer than I have been a filmmaker.

What I'm documenting can be hard to distill, because it's all around us like the air we breathe. I often need to go to a place where I can capture extreme moments.

I'm also looking for the psychological elements that fuel commodity culture. For example, if we imbue girls with deep insecurity about their bodies through images of an impossible ideal, we create a really vulnerable and avid consumer. If somebody feels that they're not OK without a certain product, you have a very deep and loyal market that will come back to the product again and again. Sometimes, this process is both rational and irrational.

My photography is often a sociological look at American culture and it's been very well published in the UK.

My first book, Fast Forward, was about growing up in the shadow of Hollywood and how kids are affected by the culture of materialism and the cult of celebrity, and I've often felt the reason my work has an audience in the UK is because it's everything the British love to hate about the Americans.

I focus on a lot of women's issues.

The people in the popular group say there is no peer pressure because they are at the top of the food chain. Really what they are doing is just eating away at everybody else.
