Less important, to me, is that Rodinal gives a sharp, but beautiful grain, whereas HC-110 looks a bit less distinct. Rodinal gives sharper edges. HC-110 gives slightly finer grain. - Thomas.

WebbIt works well with Rodinal, but be prepared for a visibly grainy result. Not unpleasantly grainy, but of the sort "this grain was supposed to be there and it is" result. My favorite development times for this combo in 135 film are: shot as ASA 400 => 11:00 minutes in Rodinal 1+50 at 20 °C; shot as ASA 800 => 08:00 minutes in Rodinal 1+25 at 20 °C
Webb6 maj 2024 · In Europe, there are two main techniques: (1) reductive amination uses the ‘aluminium amalgam method’; (2) the ‘high pressure method’ is the same technique used to produce MDMA in Europe, the only difference being the starting material (the precursor), where BMK yields methamphetamine and PMK (piperonal methyl ketone, also known as … WebbI use Rodinal at 50:1, 68degrees F for 11 minutes (I think, I'll have to look at my cheatsheet at home to be certain about this). Sometimes I use Rodinal at 75:1 for 15 to 17 minutes at 68F. Freestyle Photo had a nice cheat sheet once. It was my reference on the topic.
