Remarks on the Making of Sound Records on Lenticular Color Films

A. P. Richard

Several precautions must be observed when variable density sound records are produced on 35-mm. lenticular film. An ammoniacal glycine solution is considered the most satisfactory developer. In order to secure the necessary individual control of the picture and sound records, it is suggested that the picture record be developed in a devoloper sufficiently charged with bromide, reversed, and then bleached, cleared, and dried. The sound record should then be exposed on the slightly sensitive emulsion remaining, and the entire film then developed, fixed, washed, and dried. — For better sound reproduction it is also suggested that the height of the embossed lines in the sound track area be less than that in the picture area.
