“The color experiments were conducted in the basement of a house at 1586 E. Seventeenth St., Brooklyn, N. Y. During this time a double-coated stock and a bleach formula which had much to do with the success of the later Prizma process were perfected. From Brooklyn the Panchromotion Company moved to quarters in a vacant garage in Jersey City, N. J. By this time, a certain measure of success had attended Kelley’s endeavors, and Prizma Incorporated was formed with sufficient capital to undertake regular production.
Subsequently to 1916, Prizma sent cameramen with the Prizma filter-wheel cameras throughout the world to make travel and nature pictures. The negative films were returned and finished at the Prizma laboratory.
The first Prizma film was Our Navy, released in 1917 at the Forty-Fourth Street Theater in New York City, and also shown about the same time at the Strand Theater in that city. . . The color was produced by an additive process, using a color-wheel on the projector.
Kelley was not satisfied, however; he believed that the color could be applied directly to the film by a subtractive system. In order to carry out this idea, he entered a partnership with Carroll H. Dunning and Wilson Saulsbury, and a laboratory was opened at 205 W. Fortieth Street in New York City under the name “Kesdacolor.””
