I use Instant Mytol 1:1, mixed up just before developing. I also aim for 21 degrees (on my thermometer, which I think is Jobo-branded, so probably decently accurate). I also have a habit of not using a meter. And, in this instance, I took a guess (based on the current version of FP4+, by my FP4 expired in 1987) as to how long I should develop. I sometimes try to stick to some kind of strict methodology. Sometimes.
I will visit my darkroom in nearly 12 hours. Hard conditions. Have to drive 60 kilometers and entering a cold house then (-1 degrees in the night at the moment).
I will come back with something of course, but hopefully with some success.
Well, folks, it's great so many have posted a result but remember there's no deadline for this activity. It's totally fine to post whenever you manage to get something - no matter how much time passes. So no one is actually "late".
