![]() This filter layer serves to remove the blue light, which would expose the layers beneath it. ![]() All silver-based photographic emulsions have some sensitivity to blue light, regardless of what other colors they may be sensitized for. Beneath the blue layer is a yellow filter, composed of dyes or colloidal silver. In the classic illustrative example, there are three emulsions: one is red sensitive, another is green sensitive, and the top is blue-sensitive. Each layer is only sensitive to a certain color of visible light. Note the antihalation layer.Ĭ-41 film consists of an acetate or polyester film base, onto which multiple emulsions are coated. This diagram illustrates the layers FujiFilm has chosen for this film. This was a significant problem with early films whether the newer films are archival or not is a subject of some debate.įilm layers FujiColor Superia is an example of a C-41 process film. Due to the long-term instability of dyes, C-41 negatives can fade or color-shift over time. Processed C-41 negatives, as with all color films, consist of an image formed of dye. ![]() C-41, also known as CN-16 by Fuji, CNK-4 by Konica, and AP-70 by AGFA, is the most popular film process in use, with most, if not all photofinishing labs devoting at least one machine to this development process.
