I think every photograph has performance built
into it on a couple of levels. There’s the performance of the photographer making a picture. Converging on a spot, various preparations, getting lucky—all of this involves performance. Then you have the performance of printing the photograph. My Glass House photographs accentuate the performance
of their making by intervening with things that I put in front of the camera. I started out with a few colored filters and then gradually added more filters, then curved Mylar, clear and colored glass, and finally a scientific diffraction grating.
