Fig. 6. RCA Snowhite Evenlite vinyl screen. 16-Mrn Picture and Sound Reproduction Nineteen-fifty has been a year of marked improvement in the whole 16mm process, inspired mainly by television. A number of professional-type 16-mm projectors have been made available, with performance approaching 35mm standards. Eastman Kodak Co. has announced and demonstrated a heavy-duty 16-mm professional projector which uses the same type of intermittent sprocket movement as in 35-mm professional projectors.35-36 (Fig 7). The International Projector Corp. has described a sturdy, high-quality 16mm projector designed to meet U.S. Navy Bureau of Ships Specification CS-P-41A.37 Mitchell Camera Corp. announced a new "giant" 16-mm professional projector which offers optional high-intensity carbon arc or incandescent lamp illumination. It was designed to function with standard 35-mm sound equipment.38 Approximately 1,400 16-mm sound motion picture projectors, built to comply with the high performance required by the Joint Army-Navy Specification JAN-P-49, were put into service by the armed forces during the past year. The Navy Motion Picture Film Exchange, Naval Shipyard, Brooklyn, is employing these projectors to evaluate and accept all 16-mm prints of entertainment films procured by the Navy. The projectors are used in accordance with the Society's "Tentative Recommendations for 16-Mm Review Rooms and Reproducing Equipment."39 The prints are screened with both lead sulfide and caesium-type photoelectric cells to insure that there will be no material difference in sound reproduction when the prints are presented to the Fleet on either type of equipment.40 576 May 1951 Journal of the SMPTE Vol.56
