Abstract: Variable-area sound recording on film was originally thought to be immune from processing variations. Although the effects of exposure and density upon cross-modulation distortion have long since been recognized and well documented, the significance of developing time is generally overlooked. It is shown that the common practice of adjusting developing time to compensate for exposure errors is not satisfactory. Large errors can never be fully compensated, and small errors are shown to require overcompensation if the optimal print density is to remain unchanged. The need for further study of the effect of changes in the developer itself upon cross-modulation is indicated.
