Ap-41 Process
The Ap-41 process is an obsolete colour reversal process used generally until 1983 for photographic films such as Agfa CT18. It is significantly different from other colour reversal processes such as Ektachrome and Kodachrome Kodachrome is the brand name for a color reversal film introduced by Eastman Kodak in 1935. It was one of the first successful color materials and was used for both cinematography and still photography. For many years Kodachrome was widely used ....

Reversal Film
In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. Instead of negatives and prints, reversal film is processed to produce transparencies or diapositives (abbreviated as "diafilm" or "dia" in some languages like German or Hungarian). Reversal film is produced in various sizes, from 35 mm to roll film to 8×10 inch sheet film. A slide is a specially mounted individual transparency intended for projection onto a screen using a slide projector. This allows the photograph to be viewed by a large audience at once. The most common form is the 35 mm slide, with the image framed in a 2×2 inch cardboard or plastic mount. Some specialized labs produce photographic slides from digital camera images in formats such as JPEG, from computer-generated presentation graphics, and from a wide variety of physical source material such as fingerprints, microscopic sections, paper documents, astronomical imag ...

Ektachrome
Ektachrome is a brand name owned by Kodak for a range of transparency, still, and motion picture films previously available in many formats, including 35 mm and sheet sizes to 11 × 14 inch size. Ektachrome has a distinctive look that became familiar to many readers of ''National Geographic'', which used it extensively for color photographs for decades in settings where Kodachrome was too slow. In terms of reciprocity characteristics, Ektachrome is stable at shutter speeds between ten seconds and 1/10,000 of a second. Ektachrome, initially developed in the early 1940s, allowed professionals and amateurs alike to process their own films. It also made color reversal film more practical in larger formats, and the Kodachrome Professional film in sheet sizes was later discontinued. High Speed Ektachrome, announced in 1959 provided an ASA 160 color film, which was much faster than Kodachrome. In 1968, Kodak started offering push processing of this film, allowing it ...

Kodachrome
Kodachrome is the brand name for a color reversal film introduced by Eastman Kodak in 1935. It was one of the first successful color materials and was used for both cinematography and still photography. For many years Kodachrome was widely used for professional color photography, especially for images intended for publication in print media. Because of its complex processing requirements, the film was initially exclusively sold process-paid in the United States: customers had to pay Kodak for the cost of development when they bought the film, and independent photography stores were prohibited from developing Kodachrome photos. To develop the film, customers had to mail film to Kodak, who mailed the developed photos back for no additional charge. In 1954, the U.S. Department of Justice found this practice to be an uncompetitive violation of antitrust law. Kodak entered into a consent decree requiring they offer Kodachrome film for sale with and without the development fee, as ...
