Well, trying my never used before Paterson System 4, 2 reels with Foma 200 shot at box speed (I know, should have gone 100-160 ISO), XTOL 1:1, 23C
Went through the tribulations of loading the reels with the little roller thingies, a tank almost too tall for my modest change bag.
Decided to follow Paterson's instructions agitating the little thingamajiggie, one inversion at the top of the minute. 5:31 minutes at XTOL 1:1, si to underdevelop a fair amount (why??)
Water stop, fix 5 mins, Ilford wash (5+10+15).
Dunked reels in PhotoFlo (I know, I shouldn't...)
TWO almost BLANK rolls, and ONE very embarassed "photographer"
Back to HP5+, ID-11/HC-110B/Rodinal, my steel tanks and Hewes reels.
Too many things might have gone wrong: exhausted or dead XTOL, not enough dev time...
They say it's a sign if good luck to start your year on the wrong foot?
Happy 2021!!!!!!
