C-22 Process
Introduced by Kodak in the 1956, C-22 is an obsolete process for developing color film, superseded by the C-41 process in 1972 for the launch of 110 film and in 1974 for all other formats. The development of the film material is carried out at temperatures of around 75°F (24°C), making the process incompatible with the more modern C-41 process, which uses a temperature of 100°F (38°C). C-22 uses Color Developing Agent 3 The third in the series of color developing agents used in developing color films, commonly known as CD-3, is chemically known as N- - 4-Amino-3-methylphenyl)ethylamino.html"_;"title="-[(4-Amino-3-methylphen_...,_unlike_C-41_which_uses_ 4-Amino-3-methylphenyl)ethylamino.html"_;"title="-[(4-Amino-3-methylphen_...,_unlike_C-41_which_uses_Color_Developing_Agent_4">4-Amino-3-methylphenyl)ethylaminothyl">4-Amino-3-methylphenyl)ethylamino.html"_;"title="-[(4-Amino-3-methylphen_...,_unlike_C-41_which_uses_Color_Developing_Agent_4.

Kodak
The Eastman Kodak Company (referred to simply as Kodak ) is an American public company that produces various products related to its historic basis in analogue photography. The company is headquartered in Rochester, New York, and is incorporated in New Jersey. Kodak provides packaging, functional printing, graphic communications, and professional services for businesses around the world. Its main business segments are Print Systems, Enterprise Inkjet Systems, Micro 3D Printing and Packaging, Software and Solutions, and Consumer and Film. It is best known for photographic film products. Kodak was founded by George Eastman and Henry A. Strong on May 23, 1892. During most of the 20th century, Kodak held a dominant position in photographic film. The company's ubiquity was such that its " Kodak moment" tagline entered the common lexicon to describe a personal event that deserved to be recorded for posterity. Kodak began to struggle financially in the late 1990s, as a result of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C-41 Process
C-41 is a chromogenic color print film developing process introduced by Kodak in 1972, superseding the C-22 process. 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 photofinishing labs devoting at least one machine to this development process. Processed C-41 negatives, as with all color films, consist of an image formed of dye. Due to the long-term instability of dyes, C-41 negatives can fade or color-shift over time. This was a significant problem with early films; whether the newer films are archival or not is a subject of some debate. Film layers C-41 film consists of an acetate or polyester film base, onto which multiple emulsions are coated. Each layer is only sensitive to a certain color of visible light. In the classic illustrative example, there are three emulsions: one is red sensitive, another is green sensitive, and the top is blue-sensitive. Beneath the blue layer is a yellow filter, composed of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
110 Film
110 is a cartridge-based film format used in still photography. It was introduced by Kodak in 1972. 110 is essentially a miniaturized version of Kodak's earlier 126 film format. Each frame is , with one registration hole. Cartridges with 12, 20, or 24 frames are available on-line. Production variations sometimes have allowed for an additional image. The film is fully housed in a plastic cartridge, which also registers the image when the film is advanced. There is a continuous backing paper, and the frame number is visible through a window at the rear of the cartridge. The film does not need to be rewound and is very simple to load and unload. The film is usually pre-exposed with frame lines and numbers, a feature intended to make it easier and more efficient for photo finishers to print. Unlike later competing formats, such as disc and APS film, processed 110 negatives are returned in strips, without the original cartridge. History The 110 cartridge was introduced by Kod ...

Kodacolor (still Photography)
In still photography, Kodak's Kodacolor brand has been associated with various color negative films (i.e., films that produce negatives for making color prints on paper) since 1942. Kodak claims that Kodacolor was "the world's first true color negative film". More accurately, it was the first color negative film intended for making paper prints: in 1939, Agfa had introduced a 35 mm Agfacolor negative film for use by the German motion picture industry, in which the negative was used only for making positive projection prints on 35 mm film. There have been several varieties of Kodacolor negative film, including Kodacolor-X, Kodacolor VR and Kodacolor Gold. The name "Kodacolor" was originally used for a very different lenticular color home movie system, introduced in 1928 and retired after Kodachrome film made it obsolete in 1935. Varieties of Kodacolor-branded print film Kodacolor Kodacolor is a color negative film that was manufactured by Eastman Kodak between 1942 and ...
