C-22 process

Introduced by Kodak in the 1950s, C-22 is an obsolete process for developing colour film, superseded by the C-41 process in 1972 for the launch of 110 film and in 1973 for all other formats.

The development of the film material was 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).

The most common film requiring this process was Kodacolor-X.
