The Kodak Color Negative C-41 Film Processing Kit is designed to process all colour negative films compatible with the standard C-41 processing in small developing tanks or rotary processors. The chemicals comes in liquid concentrate form and mix with water to make 2.5L or 5L of Developer, Bleach, Fixer, and Final Rinse (select kit volume from drop-down menu).
Chemistry can be used one-shot or prepared into a separate “working” solution and “replenisher” solution. 2.5L working solution processes up to 20 rolls one-shot, and 60+ rolls when used as a replenisher solution. The 5L kit would have double this yield.
To replenish the 2.5L kit, each chemical can be mixed and divided into 1000mL of working solution and 1500mL of replenisher solution, yielding up to 40 rolls. You can also divide it into 500mL of working solution and 2000mL of replenisher solution for a yield of up to 50 rolls. You could even purchase another 2.5L kit and use all of that mixed chemistry as replenisher to process 60+ rolls.
If replenishing, extra care must be taken to avoid oxidation and contamination. Storing replenisher solutions in fully-filled chemical storage bottles is ideal. See the “Storage Conditions” section of the instruction manual for more details.
To replenish the working solutions of each chemical after each processing session, pour 40mL/roll of replenisher solution into the designated working solution’s storage bottle. Then pour in the just-used working solution from the completed processing session until you reach the original working solution volume. Discard the remaining excess chemistry safely.
