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Introduced by Kodak in the 1956, C-22 is an obsolete process for developing color film, superseded by the C-41 process in 1972 for the launch of 110 film and in 1974 for all other formats.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, making the process incompatible with the more modern C-41 process, which uses a temperature of 100°F. C-22 uses Color Developing Agent 3, unlike C-41 which uses Color Developing Agent 4.
The most common film requiring this process is Kodacolor-X.
C-22 film can still be developed in black and white.
