Detail from Mary Lucier's Dawn Burn, 1975. From sfmoma:
Lucier's seven channels of landscape video imagery record seven consecutive sunrises over the East River in New York. Aligning the horizon with the bottom edge of the television frame, Lucier videotaped the sun's gradual elevation. As its luminosity grew to exceed the video camera's tolerance level, the sun burned a spot in the camera tube. This left the camera's tube, and the videotapes made with it, indelibly scarred ... The seven tapes are shown on seven monitors, each slightly larger than the one before, presented in an obelisk-like structure, emphasizing the efflorescence of light and suggesting a relationship between the video medium and environmental resources.I saw this as part of the September 11 exhibit at P.S.1 last fall. All of yesterday's warnings about looking directly at the sun brought it to mind.
