Out of curiosity I would like to understand why photographic film can be handled in a "dark room" lighted with red light but is ruined if it is exposed to the same intensity of yellow light. In a movie, I was watching, some people were looking at some film in a dark room. They kept saying, "Make sure no one opens the door." I don't understand why regular yellow light would harm a photo.
Re: Why is film ruined when exposed to yellow light?
