Photographing events over time
Abstract: Artists and scientists have used photography to portray events occurring over a broad range of timescales, from pico-seconds to tera-seconds. I'll review some of the hardware and computational techniques used to create photographs over these different timescales. The talk addresses work by artists, photographers, and computer scientists, including the artists Haas, Salavon, Funch, Jones, the photographers Marey, Muybridge, Haas, Prokudin-Gorskii, Doc Edgerton, and research from Microsoft, U. Washington, MIT, Harvard, Google, and Berkeley. Describing events at the short time scales is mostly a hardware issue. In contrast, capturing events over longer time scales often involves tracking objects or removing changes in illumination or viewpoint, and thus is a computational problem. There is still much to be done to capture and convey events over long timescales well.
