How Safe Is Your Safelight? Eastman Kodak Company. Rochester, NY. 1985.

Abstract: The term safelight is a photography term used to describe the illumination of a darkroom. Photographic materials vary in speed and sensitivity, which varies the time they can be exposed to safelight during development. Certain film types cannot tolerate any safelight during development. A safelight is comprised of three different parts: the housing, the filter, and the bulb. This pamphlet provides descriptions and suggested uses of safelight lamps offered by Kodak. The pamphlet also lists precautions to consider when using a safelight to protect the film and preserve the quality of photographs.
