Three color components of a scene are recorded on a black-and-white film which has, for example, separate blue, green and red sensitive elements and which has been pre-exposed with blue light, with green light and with red light to a grating or grid pattern. The gratings may be recorded angularly disposed relative to one another, or if of different spatial frequencies, they may be mutually aligned for every pre-exposure. When the pre-exposed film is subsequently exposed in a camera to a visual scene, the additional component scene exposures representative of color components of the visual scenes modulate corresponding grating latent images in accordance with the color and luminance of the component scene elements. After proper processing of the film, a color image can be formed by placing the film in a spatial filtering projection system using color filters. The color image can then be recorded on conventional color print materials or displayed.
