I'm referring to 120 format here: After much APUG reading, I bought HC-110, finding Rodinal wasn't much recommended for Delta 3200 at EI3200. My first roll developed grainier than I expected and without the smooth tonality and exposure latitude that I've grown to love with FP4+ and lately, Tmax 400. My technique: dilution B [ 1:31 from syrup ], 24 min. 20C, first minute: frequent stirring, then one 5 sec. agitation per minute - stirring both directions. I'm not after high contrast. I expect more grain than from the slower films - which really don't have any visible to me in 6"x6" prints. Since I've been having great results with Rodinal at 50+1 and 80+1 dilution, I'm seeking suggestions to direct my next developing experiments. Greater dilution of HC-110? Less agitation? Both? Use Rodinal? Given enough time, I could work through various permutations. There is such a wealth of generosity and knowledge here, I thought I'd ask for advice. One more thing: Most days, I would have enough film speed [ in my Rolleicord Vb ] at EI 1600, or EI 1000. EI 3200 is useful in twilight and dark fall days, which are the majority here. Thanks in advance.
