Red light is used in developing photographs because it has the least effect on light-sensitive photographic materials, such as film or photo paper. This allows photographers to work in a darkroom without exposing their materials to white light, which would ruin the photos being developed.
energy level that is less likely to trigger the chemical reaction in the film. This helps prevent premature exposure and preserves the integrity of the film during the developing process.
