The Calbe Color C-41 Kits offer a colour development process in three steps: colour development (CD), bleach-bix (BX) and stabiliser (STAB). The kit consists of six components, being the colour development in three parts, the bleach-fix in two parts and the stabilizer bath. The mixing of the baths themselves is straight forward. The three components of the colour developer have to be mixed with each other before use and supplemented with water to reach the complete bath. The 2.5L kit comes in three bottles of 500ml each, which must be diluted with 1L of water. After mixing, the bleach-fix should be diluted with 1.5L of water. The stabilizer with 2L of water. Of course you can also choose not to make the complete bath and for example only make 1L working solution. In that case you use 200ml of each component colour developer, dilute with 400ml of water and so on. After development, store the created baths in light-proof (accordion) bottles and, if necessary, treat them with an anti-oxidation spray such as Tetenal Protectan to maximise the storage time. The biggest enemy of photochemistry is oxygen, if oxidation can be reduced to a minimum, the chemistry will keep the longest. The storage time of created colour developer is about 6 weeks (longer with anti-oxidation spray) and for the other baths about 24 weeks.

The Calbe Color C-41 Process can be used at three temperatures: 30 °C and 38 °C. The process at 38 °C is the standard process and is only recommended if you use a tool that provides a constant rotation of the tank such as a colour processor from Jobo. The process at 30 °C is mainly suitable for home development in an ordinary development tank by hand. It is important to agitate continuously, if necessary use the agitation rod that came with your (Paterson) development tank. Before you start the process it is important that you preheat your development tank by filling the tank (with film) with water at a temperature of 30 °C for about 5 minutes and then pouring it out. If films are pushed to higher speeds, the development can only be done at 38 °C and each step has to be extended by 30 seconds.

With the Calbe Color C-41 Kit of 1.2L you can develop approximately 18 35mm or 120 films at a speed of ISO 200 or lower and 15 to 18 35mm or 120 films at a speed of ISO 400 or higher. Keep in mind that the developer will run out considerably faster if films have a speed equal to or higher than ISO 800. Maximum capacity is achieved if at least 4 films are developed simultaneously in at least 1L.
