Rhythm 1, black and white 16mm film (un-split Standard 8mm), 4 minutes, sound, 1974.
Rhythm 1 permutates four possible camera – subject relationships; still camera and moving subject, vice versa, still camera and still subject, moving camera and moving subject. Each side of the film was exposed twice, using a hand powered propellor in front of the lens to arbitrarily generate three possible combinations of image; no exposure, single or double exposure. The sound track is the noise of the sprocket holes (48 per second @ 24 fps projection speed).
