Positive-Negative (2 minute excerpt)
b&w, 12 min. silent
Positive-Negative was made in the video studio of the Medical Studio at the University of California, San Diego, and projected during alive performance in the Art Department there. It was the first tape Sonnier shot in a television studio with the help of technicians and elaborate mixing equipment. Two large studio cameras and one-inch tape were used, and the lighting and technical facilities available mitigated the need for objects which in the earlier situational tapes ad functioned as light modifiers or performance props. Rather than the camera being stationary and the activity dependent on one camera view, the set now remains stationary and the dial cameras, properly mixed, alter scenes instantaneously. In Positive-Negative, the two cameras frame the performer's head rotating full circle so that complementary views of it are seen simultaneously, on each half of the split screen, one in positive and the other in negative. As the performer turns, the cameras independently pick up her face and the back of her head, or her left right profiles, so that a constant binary relationship is maintained. Camera solarization (causing image disintegration), wipes, dissolves and, at the end of the kinescope, superimpositions, alter figure-ground relations.
