Caffenol is a photographic alternative process whereby phenols, sodium carbonate and optionally vitamin C are used in aqueous solution as a film and print photographic developer. [ 1 ] [ 2 ] Other basic (as opposed to acidic ) chemicals can be used in place of sodium carbonate; however, sodium carbonate is the most common.
In the RA-4 process, the bleach and fix are combined. This is optional, and reduces the number of processing steps. [12] Transparency films, except Kodachrome, are developed using the E-6 process, which has the following stages: A black and white developer develops the silver in each image layer. Development is stopped with a rinse or a stop bath.

C-41 is a chromogenic color print film developing process introduced by Kodak in 1972, [1] 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, if not all photofinishing labs devoting at least one machine to this development process.

In chemical engineering, process design is the choice and sequencing of units for desired physical and/or chemical transformation of materials. Process design is central to chemical engineering, and it can be considered to be the summit of that field, bringing together all of the field's components.
