I guess there's a first time for everything. I have never had a single problem with my Unicolor C-41 kits. I usually toss them because I am afraid of a catastrophic collapse of activity, but I have never actually had it happen. Until, that is, today! And here's the kicker... I usually do one or two rolls at a time, but today I had 3. One was even a roll of Eterna that I went through the remjet removal pre-bath with. I usually have the "oooh, it worked again!" moment when I pull the spool out of the final wash. But today I had a "ooohh?? huh?" moment when I couldn't see any frame borders. Then it all looked kind of well, light-ish. A closer look confirmed that there were absolutely no pictures to be had. So, it's a sad day for me, but I think I will take this as a sign that I should start making my own C-41 and ECN2 developers. That sounds reasonable, right?
