The idea of the portrait itself is my great love. The questions and answers in it can go on forever and ever. It is what happens in the eyes or with a tilt of the head. I keep going because it's too interesting to stop.

Does getting closer to the subject make the photograph more intimate? I'm sure it takes more than that. What comes next? The face, the nude? That's what I'd love to do. Who would even let me do that?

I'm at the point now where I don't really have an agenda. I kind of let things flow, and there's not a narrative. On the set it's usually one or two people, and I'm not trying to choreograph them as I did in the past. I'm really just trying to see what's going on in their minds and in their faces.

The conservatism is extraordinary to me; just compare the way they dress to the way their parents dress. There are still no tattoos or piercings, which is interesting to me. Why does everyone who lives in one place dress alike, look alike, eat the same thing, and decorate the same way?

I never thought that my work was going to become well-known. It started happening slowly, without my realizing it. But when I did, it was terrifying. I still can't believe that people let me photograph them. The trust is amazing. But I've always put them in a context that is dignified, and that's really important.

Shooting great-grandchildren of some of the people I had photographed in the past, who are around the age of 15, is fascinating to me, because they're right on this fine line between still being children and starting to become themselves.

My theory is, the more pictures you take, the better you get. It's like a sport. I never wait to get a particular shot because wonderful accidents can happen when you shoot a lot.
