      It has it in the name

      As it says, it’s colour simplified, easy to mix, easy to develop. I bought a £30 sous vide to use in my developing and it works a treat in combination. The only thing that I could fault it on is that the blix lasts longer than the developer, but that’s hardly an issue.
      Colours that come out are great, I’ve used it on c-41 film and motion picture (with remjet removed with a baking soda bath).

      Wow! So pleased with my first ever colour processing

      I've never developed colour film before but have developed a fair few black and white rolls using the Cinestill DF96 kit. I bought this along with the Cinestill temp control system. I processed 8 rolls back to back using a lab box & couldn't be happier with the results. I'm not sure I'll ever actually use a lab again for developing or scanning.

      Simple and effective

      I usually use unicolour for my colour chemicals so was a little hesitant to try something new. But it was easy to mix up, following clear instructions and they did the job perfectly.

      Worth it for anyone wanting to try developing at home.

      Great Colour Film Developing Kit

      I bought the Cinestill CS41 kit to try it out after getting started at colour developing with the Film Photography Project Unicolor kit. The Cinestill CS41 kit was easy to mix up but make sure you wear gloves and a mask and open the window as the Blix (bleach/fix) powders have an exothermic reaction and get hot and stinky when mixed. Safety first. The kit comes with full instructions on how to mix and use the kit properly with developing times for your colour film. Great value for money and very simple to use.

      Excellent kit with decent capacity if stored properly

      This is the second C-41 kit I've tried, and the first that uses powder. I was a little apprehensive, but the powder dissolved easily without any issues. I did about 4 rolls per session, about a week apart. This week I stuck a couple of “dud” rolls in that I wasn’t expecting much from, because the chemicals were about 4 weeks old now but they came out OK as well. I kept them in brimmed brown glass bottles and didn’t notice any deterioration through that timescale. I’m going to stop now, though! I think I got 6 rolls of 135-36, 7 rolls of 135-24 and a roll of 120 from this batch. I used the TCS-1000 immersion heater in a mop bucket to keep the temperatures about right, which was straightforward enough. Annoyingly, the best colours were from Fuji Superia 200 which has been discontinued for ages(!)
      TLDR: I can recommend the FPP C-41 kit!
