Viscous-Layer Processing of Variable-Area Sound Negatives

Variable-area sound recordings made on Eastman Television Recording Film, Type 7374, can be processed on the Eastman Viscomat Processor, Model 20, in one minute. In comparison with conventional immersion-processed sound negatives, improvements in signal-to-noise ratio, frequency response and optimal negative density latitude are obtained with the viscous-layer processed Type 7374 negatives. Release prints on Eastman Fine Grain Release Positive Film, Type 7302, can be processed using the same viscous developer that is used for the sound negatives.
