The art of sound pictures (1930)

COLOR 257 print with respect to the saturation or amount of color in the pictures developed. In the dye process, as we have noted, different amounts of dye may be absorbed, depending upon the length of time the film remains in the dye bath. When the chemical conversion process is used, however, it makes no difference how long the film is left in the chemical solution used to convert the picture image. The conversion process runs to completion, and then stops, so that no further chemical action takes place on the film. The pictures obtained by this process are more clearly outlined because the imbibition process need not be used. There is no transferring or lithographing in the process, which would tend to result in blurred outlines or blotting paper effects on the final prints. The Multicolor process has, also, certain commercial advantages. It can use, as we have already noted, any ordinary camera without costly special apparatus. New Multicolor camera attachments and magazines can be made to order very quickly, and cost only a few hundred dollars as against the thousands required to build special color cameras. This makes the Multicolor process much simpler and enables the company to deliver the finished prints with comparative speed. With the primary colors used by Multicolor, namely orange-red and blue, it is impossible to get a bright red on the screen, and its greens tend to have too much of a blue-green tinge. Multicolor has the same difficulty that Technicolor experiences in getting pure yellow, although Multicolor can get a remarkable gold on the screen which is very close to pure yellow. Multicolor experts apparently can get a very good yellow when the color and lighting conditions on the set are exactly right. Multicolor and Technicolor have the same difficulty with helio
