Eastman Kodak's New Print Format Boosts 8mm Utility An experimental format for 8mm motion pictures for educational, industrial, and commercial purposes was described by two Eastman Kodak Company men recently before the Society of Motion Picture and Television Engineers. Their report was made in response to growing interest in commercial 8mm prints in the trade. E. A. Edwards and J. S. Chandler, both of Rochester, N. Y., said that their theoretical study of a modified 8mm format had the objective of getting the best quality sound and picture from 8mm film with minimum added cost. It provides a projected image with approximated 50 percent more area than present 8mm. In a study of the four major functions of the film — pictures, sound, indexing, and guiding — they found that the present 8mm formal uses oiil\ 17 pi'iicnl <>f the film area for picture image. Thev were able to raise this to 63 percent for the experimental format. This was accomplished by reducing the size of the perforations and placing the perforations nearer the edge of the film. The sound track was also moved to the opposite edge of the film from the perforations. After extensive testing they arrived at an 8mm strip of film with 36-mil wide perforations spaced 20 mils in from one slit edge of the film, a somewhat larger pitch of .1667 inches, and a magnetic sound track 30 mils wide along the other slit edge of the film. This leaves 228 mils down the center of the strip for the picture. One of their objectives with the experimental 8mm format was compatibility, so 16 mm originals or masters can be reduction printed onto the 8mm film. According to their design, the 16 mm image will fit the width available on the new experimental 8mm film at a reduction of 1.8 to 1. iP New Process Handbook Describes Film Aging Blemishes Over the years the National Bureau of Standards has conducted considerable research on the permanence of record materials, including both paper and photographic film. Recently, microscopic blemishes have been found on microfilms; apparently they had developed after the film was put in storage. Practically no information loss has been observed, but any potential threat to the permanence of Government records is a matter of concern not only to the National Bureau of Standards but to records officers throughout the Government. There is much to be learned from these blemishes and they are being studied in many laboratories. A report on findings is contained in Inspection of Processed Photographic Record Films for Aging 'Blemishes, by C. S. McCamy, National Bureau of Standards Handbook 96, available for 25c from the Superintendent of Documents, U. S. Government Printing Office, Washington. I).
