Product Information
CineStill Cs41 "Color Simplified" 2-Bath C-41 Powder Kit gives home photographers a powder-concentrate workflow for processing color negative film. Mix the Cd41 Color Developer and Bf41 Bleach&Fixer Bath with water to make one liter/quart of reusable chemistry for up to 24 rolls.
Made for home C-41 processing
The kit is designed for use with standard processing tanks and reels, so no special processor is required. CineStill recommends 102°F processing, while its instructions also cover lower-temperature processing with longer times and push/pull processing.
Two-bath chemistry with reuse guidance
For repeated use, CineStill calls for increasing Developer time by 2% for each roll previously processed. The Blix time does not need to increase through reuse. A separate stabilizer bath is not required for modern color negative film stocks in this simplified process.
Powder concentrate format
The powder concentrate is intended for compact storage and a longer unmixed shelf life when stored properly. CineStill recommends dissolving the powder in warm or hot water before processing.
