Processes of Photography in Natural Colors

Although a simple process of color photography yielding a print which faithfully reproduces the colors of nature is greatly needed, most of the research at the present time is being directed to the perfection of color motion pictures. Another equally important field is the use of color photography in photomechanical printing processes, as colored illustrations have come into very extensive use during the past fifteen years. The work of different investigators may naturally be divided into (1) still photography, including color photographs to be viewed by transmitted light and by reflected light, and (2) motion picture color photography. — Almost from the first years in which motion pictures were used commercially, about 1895 to 1900, experimenters have been working on methods of producing them in natural colors. The only practical processes enjoying any extensive commercial use in the theaters, however, are subtractive processes in which the color is incorporated in the film. These subtractive processes, however, are only two-color methods and therefore a true spectral record is not realized. — One additive process has had extensive application for amateur motion pictures for over two years. Within the past year a large number of color motion pictures have been released with sound accompaniment so that the ultimate is being approached in motion picture photography, namely, pictures in color and sound.
