Vesicular Photography for the Motion-Picture Industry
Robert T. Nieset, N. T. Notley · Journal of the SMPTE · 1965
When motion pictures are printed on vesicular film stock, development is by dry heat and the process is negative/positive. Newer systems which may find use in the motion-picture industry comprise full reversal processing for positive/positive copying, and a new film which requires only a single overall exposure to a flash-tube for its processing, development and fixing together. The film gives direct positive to positive copy, has high resolution and capability for several generation copying, and contrast is controlled by input to the flash.
