Abstract: Motion picture film may become spotted with mineral oil in one or more of the following ways: (1) in the camera during exposure; (2) during passage of the film through a printer or processing machine; (3) when squeegeeing with a pneumatic squeegee previous to drying; and (4) during drying with compressed air containing atomized oil. If the film becomes spotted with oil previous to processing, the oil acts as a resist and causes uneven development. If the oil has access to the film during drying, the drying of the gelatin is locally retarded and spots similar to moisture markings are produced.<sup>1</sup>
