Okay, I’m convinced.
From the same chemistry, Tri-X blacks whallop HP-5’s.
Tri-X rated 100-400, expose for the highlights, Rodinal 1+25 for 11 minutes at 20C, gentle rolling the tank every 90 seconds.
Same Nikon, though this time with the 50mm. But really: a big difference.
Okay, Oh Great Yellow Father, this time: you’ve earned your extra buck-a-roll.
