Abstract: During the course of Samuel B. Grimson's investigations of the line-screen and the color reseau methods of color motion-picture photography, the production of perfectly sharp and even reproductions of the color screen elements in successive frames of the negative film presented a major problem. This paper describes a mechanism, adaptable to the Mitchell camera, by which the desired results are obtained. Although this mechanism was designed primarily for use in Grimson's color processes, it is also useful in other applications where maximum sharpness is important.
