Color-reversal film produces an image that is referred to as a negative, because it is the opposite color-scheme of the true to life image. It is similar to when Spiderman entered the negative zone and his suit’s colors were reversed. For example, when viewing negative images under light, what is seen as red will be printed as green and what is seen as blue will be printed as yellow. The resulting images will often have an orange-tint caused by masking dyes used to correct color-errors in the film. Color-reversal film is also referred to as grain-free film, because it undergoes a bleaching process in development that removes all exposed silver from the film. Color-negative film is more forgiving in regard to light exposure errors than slide film. C-41 is the chemical process in which color-reversal film is developed.
