Recent American Standards for 16- and 8-mm Emulsion Position

The three most recent American Standards to appear in the new format are 222.10,222.16, and 222.22. The first two concern Emulsion Position in 16-Mm Silent and Sound Projectors, respectively, while the third is on Emulsion Position in 8-Mm Silent Projectors. With the exception of titles, which were brought up to date, they are identical with the previous standards which carried the 1941 approval date. The absence of change might imply that the emulsion-position situation has remained static over the intervenening years, but this is far from being the case. Actually, the question of whether the film emulsion in normal l6-mm projection should face the screen or the light source has been the subject of considerable discussion, particularly as regards sound release prints. Sixteen- and eightmillimeter silent films are a parallel problem but they are less important economically and are far less critical from a technical viewpoint, so whatever is adopted for 16-mm sound will probably be adequate.
