The term "safelight" describes darkroom illumination that does not fog a light sensitive material, under the condition for its handling and processing. Generally, a safelight filter is chosen which transmits light at low intensities so as not to expose the photographic material.
For best results, follow the manufacturer's safelight recommendations.
