Hello all,
I am so far successfully using the C-41 film development kit to develop my 35 mm color films. I keep the solutions in well closed glass bottles filled to the top. So far the chemicals seem pretty stable there, but I wonder how do I see when one of them - either developer mix or Blix - decomposes? I would expect to see a color change in the yellowish developer, but how do I know if the Blix is still okay since it has a dark red color? Any precipitate appearing at some point? Also, I see a little bit of brown precipitate formed in the developer storage flask, but it fully dissolves when heated up to 39 deg C. I suspect this is normal?
Other question related to this: can I use the same Blix prepared for RA-4 printing process also for the C-41 development and vice-versa?
