I think making features has got to be in the addiction category.

The challenge has always been to wrest emotion out of a doll face that we think of as only having one emotion. It's moving a light, moving my camera; it's just this mental investment that I make, and suddenly, everything changes.

I feel like I spent so much time trying to understand my identity and my identity as an artist. But when all is said and done, at this age, I feel the most like I felt when I was 11. And all those talents I had when I was 11 and 12 - I'm letting them sort of happen again. I can't speak for men, but for women - we go back to a kind of pre-adolescent state when we were superfree and supercool.

The visual world has blown up, the world of writing has blown up; there's so much text online. Anyone and everyone can express themselves. It's a lot to think about as an artist. Also, that the persona of the artist might actually be of some importance. When I came of age, it was important to be quiet and hang back and be mysterious. I knew artists who didn't even want to show up at their own openings. They never wanted to have their picture taken, didn't want to autograph a book, didn't want to answer a question. I came of age in a world where it was "Let the work speak for itself."

The thing I wondered about so much as a young artist, particularly when things weren't going well and I was really struggling, was, "Will I know when to give up? Will I know when I've suffered enough rejection? Will I know when to get out?"

I teach a graduate photo seminar at Yale, and I sometimes feel so overwhelmed by the task the students set before themselves to be artists, because - it seems so quaint, but when I picked up a camera with a group of other women, I'm not gonna say it was a radical act, but we were certainly doing it in some sort of defiance of, or reaction to, a male-dominated world of painting.

I'm very interested in stopping time. And starting time. There is that aspect of time that I'm playing with, that it's elusive and unnoticed yet really in the end the most important thing.
