A Semi-Automatic Timing Device for Motion Picture Negatives

J. I. Crabtree, C. E. Ives, Fordyce Tuttle

A motion picture sensitometer, commonly called a “timer,” is a device for making a series of single picture frame trial exposures through a motion picture negative which exposures correspond to those given by the various steps on the printer. The exposed film is then developed and the correctly exposed picture frame selected by judgment. The exposure which this frame received indicates the correct exposure to be used in the printer.
