Interesting. Never even heard of test strips before. Will read up on those. thanks.

In total this batch of chems had developed 20x rolls. These two were numbers 21 and 22. I read that if the roll comes out clear, and you cannot see the side markings that indicate the film type, then it's chems --- and that if you can see the film type markings but zero photos, you messed up in exposing/loading. This is contrary to what you're saying though, so not really sure which to think upon.

Hey everyone, New to the forum and analog photography. I've thus far developed 20 rolls successfully using my Cinestill C41 quart kit, but yesterday experienced my first time pulling out entirely blank rolls. While I know developer and chemicals can expire (these were in air tight, compressable storage for 3 months...so stretching it), I had used them just a week prior and they worked fine. Has anyone else experienced such a steep drop off / "death" of their chemicals? I would have thought since the last four rolls developed came out fine, that at the least these would have been faded rather than completely blank. The film was loaded properly as well, so no miss fires or mistakes there. Just came out entirely blank. I now have Tetenal C41 liter kits (I live in Sweden, so this is all available here atm) and intend on developing 5 rolls at a time with ideally 15 in total as the kit affords 12-16, but doing this much closer together in time (not keeping chems for 3 months). Looking forward to hear if anyone has experienced the same, any tips for me going forward, etc. Thanks in advance!
