A few days ago, the photo-science geniuses from Rochester Institute of Technology conducted their annual Big Shot, an experiment in painting with light. A scene is chosen--this year, the Smithsonian Museum of the American Indian on the Mall in Washington, D.C. The public is invited to participate by bringing handheld light sources, such as flashlights or candles. Streetlights, security lights, and other nearby high-tech sources of illumination are extinguished, so when night approaches, the scene gets darker and darker.
Inside lights are switched on to make the building glow in the dark. Then the crowd is arranged so that all the handheld lights paint the scene. This year, about 800 people participated, and after a 20-second exposure, the big shot came out pretty as a picture.
That's the Washington Monument in the background, leaning to the left because of distortion caused by the wide-open lens.
