Final answer:
Yes, a safelight can affect photographic film if it is held too close because films are sensitive to light and while safelights emit low-intensity light, it still has the potential to fog or expose the film.
Step-by-step explanation:
The question relates to whether a safelight's light can affect the film if it is held too close to the light. The answer to this question is true. Safelights are designed to minimize the amount of light that can fog photographic film or paper, but they are not completely safe for an unlimited time or at a very close distance. Films used in photography are sensitive to light and a safelight emits light at a low intensity and usually with a color filter that reduces the range of wavelengths that can affect the film. However, if the film is held too close to the light, even this filtered light can affect it, causing it to fog or expose.
