"Motion Painting" was the last film finished by Fischinger. In essence it documents the activity which took over much of his days... oil painting. For every brushstroke, Fischinger clicked off a frame of film.
Oskar Fischinger’s Motion Painting 1 (1947) is a good example of a general approach to using saturation and brightness structurally. In the first section especially, the movement of color is important as it builds large phrases. In the film, we see a single painting develop layer upon layer over eleven minutes. We feel tensions resolve in short phrases as we see shapes developing as motives, begun and then brought to completion. Spirals coil and unfold; mosaics of diamonds appear and cover what is underneath. Larger structures are perceived as repetition and contrast of hue choices. Tension resolves as high saturation, and bright colors give way to darker colors and lower saturations.
