A Motion Picture Negative of Wider Usefulness

P. Arnold

Superpan negative film represents a refinement in film manufacture rather than an invention of startling novelty. The anti-abrasion surface coating protects the emulsion from physical harm, and the anti-halation, gray back-coating, underlying the emulsion, preserves the definition and photographic quality. Possessed of adequately high speed, the emulsion produces superior fine-grain results not common to super-sensitive films. A long gradation scale enhances the fidelity of tonal rendition, and an especially wide latitude in both exposure and development increases the range of pictorial possibilities. A high sensitivity to color, carefully balanced throughout the visible spectrum, permits normal rendering or the attainment of desired color emphasis by the use of filters without demanding serious speed sacrifices.
