Why does red light not affect film development?
Photographic film is by it's very definition sensitive to light. Different types of film is sensitive to different colour spectrum The first types of film had a very limited sensitivity to colours and only reacted to blue light. As technology progressed film was made sensitive to a wider spectrum of light.Orthochromatic film was (is) sensitive to colours from blue to green, thus not sensitive to red light hence not affected by a "red light" during development.This film type was, however, superseded by "Panchromatic" film that is sensitive to all light spectrum, including red light. This means that most (modern) film cannot be developed using a red darkroom light without permanently destroying the film.Copying images (to paper or plastic sheets) is a different matter as the light sensitive emulsion on copy-paper is notsensitive to red light which is why a red light can safely be used during copying and development of the copies.
