Use of a Motion-Picture Printer as a Sensitometer

Robert O. Gale, John J. Graham

A Bell & Howell Printer, Model D, can be used as a sensitometer for exposing process control strips in small laboratories or for emergency work. The variability in exposure of a printer was only slightly greater than that of a commercially used sensitometer, when the instruments were compared under carefully controlled conditions. Procedures are described for the selection and storage of check film stock, printer control, monitoring and control of illumination, and making controlled exposures.
