Default Longevity of C41

I have an idea that someone somewhere has 'tweeked' the most recent C41 developers anyway that give them a much longer life. I stopped using Tetenal a while back because I was having difficulty in finding a middle sized kit and went back to Digibase.

I opened a 5 l kit way back in April this year and pre-mixed an amount of developer that would see me over a period when stored in full sealed glass bottles. That was used up so went to make some more and was very surprised to find that all of the chemicals in the three bottles were as clear as crystal. even though they had been opened almost 6 months before. They also worked perfectly well with no colour imbalance.

The only difference I could tell was in the kit itself they now include a bottle of 'starter' previously it would have been pre-mixed. So the tablet form is ideal for travellers who want to process on the run so to speak is a good idea here is a good alternative. (So long as you are not flying).
