The class that I teach is called "The Life of a Photograph." It takes up the question, of the billion photographs that were taken today, how many will have a life, and why? So the new reality has made the question more pertinent, not less pertinent.

First of all, I appropriate photographs.In presenting the Richard Prince photograph I tried to be as neutral as I could be. I put down the fact of it. I wanted it to be the same thing he wanted it to be, an open ended invitation to think about authorship, and who owns a created work. So I pair it with my appropriated picture.

There are a lot of ways to be expressive in life, but I wasn't good at some of them. Music, for instance. I was a distinct failure with the cello. Eventually, my parents sold the cello and bought a vacuum cleaner. The sound in our home improved.

[In the late 80's] that's the first time I heard about that astonishing idea [that most photographs would be taken on telephones]. And now I've been watching the tsunami of images.

But there is more to a fine photograph than information. We are also seeking to present an image that arouses the curiosity of the viewer or that, best of all, provokes the viewer to think-to ask a question or simply to gaze in thoughtful wonder. We know that photographs inform people. We also know that photographs move people. The photograph that does both is the one we want to see and make. It is the kind of picture that makes you want to pick up your own camera again and go to work.

When assignments were over, photography continued. One of the primary reasons it did was that I wanted and needed to have fresh work. Also, it's very stimulating to be around non-professional photographers. They're the ones with the purest flame burning about their photography. I appreciate that.
