A lot of times I had footage that didn't have sound [in the Dream of Life film] - either I didn't bring a sound recorder, or I forgot to turn on the sound recorder - so we would have to improvise and build those scenes.

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.

It took 12 years to put this film [Dream of Life] together, but it was not until toward the end of those 12 years that I looked at Patti [Smith] and said, "Maybe we should do something with this footage."

The only self-consciousness in the film [Dream of Life] is anyone's natural shyness.

I thought about how to film something, how to take pictures of it and how to mix it all together. And I was getting that through Patti [Smith] - because she takes pictures, performs, writes; she does so many things, and that was a big inspiration to me. It helped me realized that I'm not just a fashion photographer. I wanted to do all these other artistic things as well, and during filming my mind opened up to those possibilities.

Sometimes my fashion pictures can look a little bit like documentary style pictures. So having a camera in my hand was normal.

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.
