Fashion's been really good to me. It financed Patti Smith: Dream of Life.

At the beginning I didn't even really think about making a movie [Dream of Life]. I was just thinking of documenting somebody.

I would bring Patti [Smith ] in to the editing room [working on the Dream of Life] and say, "This is a great moment for a voiceover, or a poem," and then we'd bring in some sound design.

Because the filming process was so organic and there was no script, the film [Dream of Life] was literally telling us what it wanted to be in the editing room.

There are a lot of layers in the film [Dream of Life]. And during editing we would try to tame all the layers, try to make things a little bit more understood. We would move scenes around. We'd try all these things.

I wasn't familiar with Patti [Smith ]much at all. When I was asked to photograph her, my wife said, "Oh my God, Patti Smith!" So I looked at some Robert Mapplethorpe books and I recognized those pictures.

Fashion has also been a great outlet, and I'd like to do more fashion photography in the future. I also photograph a lot of artists.
