Develop c 41 film1/10/2024 ![]() I am very familiar with processing/chemistry and methods, using individual tanks/ deep tanks (48 rolls of 120 at once) and dip and dunk machines (E6, we had no use for C41). Quote:Phil, by changing development time, we can vary the contrast as well as effective ISO. What is relevant is when the OP becomes familiar with processing and what a good negative looks like for scanning (Because of the dye printing onto traditional paper would probably be a non starter) then a series of clip tests would be in order. You could set the camera to P for professional, set the drive to continuous and expose the whole roll at an "average" subject.Įrr and the point of your post is.? I'd invest in a complete roll for clip tests. Higher temperature gave shortened process times which reduced the labour costs. We used deep tanks that sat in a thermostatically controlled water bath and many labs used machines. The C41 process was designed for professional use. It was also easier to maintain the lower temperature when doing his processing in the kitchen sink. I've just remembered that, when my old school housemaster switched from C22 to C41, he used to develop his C41 films at the same temperature as the old C22 because it gave a more convenient process time. Phil, by changing development time, we can vary the contrast as well as effective ISO. Only then would I look to doing some clip tests in order to determine the optimum dev time for your film. If you already process your own black and white film, with this kit, there is no reason not to process C-41 color negative film at home as well It is specially formulated without compromise for modern color films, not requiring a stabilizer bath. The results will be interesting but I certainly would not recommend trying this if you have no experience of processing and would certainly practice using standard B/W film till you are familiar with the process and importantly what a good negative looks like. The other factor is that the resultant negative is only suitable for scanning due to the dye in the base (Photographic paper is not very sensitive to the orange/red end of the spectrum). This chart is for XP2 (a chromogenic B/W film that is normally processed in C41 chemistry) that gives a rough idea of times.XP2 processing times in B/W dev It is also agreed that the contrast will be lower but with a finer grain structure and a greater tonal range. It seems to be agreed that the development time will be longer for C41, only experimentation can determine the optimum time. Have been doing some more research into this.
