New One-Strip Color-Separation Film in Motion Picture Production

A description is given of procedures to be used with the new Ansco Film Type 155—which is designed for making color-separation negatives. Equal gammas are obtained for the red, green, and blue filter exposures with the same developing time, making it possible to obtain the black-and-white separations as successive frames on a single strip of film and thus obviate much of the difficulty of registration. By varying the developing time or developer formula, it is possible to change the gamma over a range of 0.5 to 2.0 to suit the purpose for which the separations are intended, while still maintaining equal gradations for the different filter exposures. — The following are some of the applications for the film which are described: (1) to provide duplicates of Ansco Color originals for protection or (2) foreign release, (3) for special-effects and process photography in conjunction with Ansco Color motion picture films, and (4) for direct photography of animated cartoons which are to be printed in Ansco Color.
