  • Patent number: 4522475
    Abstract: An apparatus and method for showing motion in a single color photograph in which motion of an object is shown by displaced images of the object in different colors. The scene to be photographed is illuminated by a light source including a plurality of light units emitting light of differing spectral composition. The light units are individually and sequentially activated, the light emitted from all of the units appearing to be emitted from substantially the same location. The flashing of the light units is controlled by a timer. The resulting photograph shows the non-moving objects in a color which is the composite of the spectral composition of all of the light units, typically the natural color. The movement of an object is shown by a spaced series of sharp images of that object in a variety of colors. The color sequence corresponds to the sequence of the flashes of the light units.
