Reproduction of Color Film Sound Records

The question of a sound record on color film seemed to have arrived at a final solution, because only a few of the proposed color film processes satisfied the constantly increasing requirements, and therefore the possibilities for sound recording became less numerous. Silver sound tracks were recommended for the more successful color film processes, as for example, in the case of Agfacolor film, where by means of a special protecting method, a black-and-white instead of a colored track was obtained, or in the Technicolor process, where black-and-white stock already containing the sound record served as a base on which color transfers were made. However, this technical development was interrupted, when, for reasons of simplicity and perhaps of cost, it was tried in the Agfacolor process to produce a colored sound track exactly in the same manner as the picture. The following discussions deal with the phenomena occurring in the reproduction of such colored sound tracks. In conclusion and for the evaluation of the results new types of photoelectric cells will also be discussed.
