Effect of Winding on the Projection Performance of 35mm Motion-Picture Film

Projection performance depends greatly upon the diameter to which the film has been wound on a reel or core prior to projection, and the effect is more obvious for film wound emulsion-out. Screen-image quality differs considerably between the head and core ends of a theater print, but if the film is kept wound emulsion-in, the focus stability is substantially improved, particularly in the larger, higher-intensity installations. These effects have been examined in a continuous series of practical studies. Extrapolations are suggested from the 35mm experiments to all projection formats.
