A Study of the Markings on Motion Picture Film Produced by Drops of Water, Condensed Water Vapor, and Abnormal Drying Conditions

J. I. Crabtree, G. E. Matthews

WHEN droplets of water come into contact with motion picture film either before or after the film is exposed and previous to development spots are formed which later appear as objectionable defects on the film. Markings are also apt to be produced if all superfluous moisture is not removed from the film before drying or if the rate of drying is changed during the progress of drying. Moisture spots are always produced on the emulsion side of motion picture film and never on the base side, since the film base is resistant to moisture.
