Final answer:
It is true that film fogging can result from improper safelighting, as safelights must provide illumination without causing unwanted exposure to sensitive photographic film.
Step-by-step explanation:
The statement 'Film fogging results from improper safelighting' is true. When photographic film is exposed to light, it records that exposure. The role of a safelight in a darkroom is to provide illumination without causing unwanted exposure, or 'fogging', of the film.
Safelights use a certain wavelength of light that the film is not sensitive to, typically red or amber. If the safelight is too bright, improperly filtered, or if film is exposed to it for too long, fogging can occur, where the entire film surface becomes exposed, ruining the intended image.
