What type of light is used during the handling of developing film?

When developing dental films, it is crucial to use safe or darkroom light to minimize exposure and prevent fogging of the film. Safe light refers to a specific type of lighting that emits a wavelength of light that does not affect the sensitivity of the film. This allows the handler to see what they are doing without compromising the integrity of the film being developed.

Using daylight or white light can lead to immediate and significant fogging of the film, resulting in compromised images that may not be usable for diagnostic purposes. Infrared light is also not suitable as it does not correspond with the safe handling requirements of developing film. Thus, the only appropriate lighting for handling and processing films in a traditional darkroom setting is the safe or darkroom light, which is designed for the specific purpose of aiding visibility without negatively impacting the film quality.
