The use of Rodinal is most common with Semistand Development. I've been playing with Semistand development on and off for a while with the more common Rodinol. Yesterday I gave HC110 a try. And I liked it. Dilution: (from syrup): 1:120 Temperature: unmeasured Prewash: time unrecorded (maybe 5 minutes) Time: 40 minutes Inversion: first 30 seconds or so, then one more time roughly 20 minutes (half way) into development Equipment used: My old trusty JOBO 4x5 drum, Kodak HC-110 (duh!), Lauder fix, lots of water Film(s): these show only Fomapan (Arista.edu) 4x5 samples, but the exact same shots were done with outdated Agfapan 100, Kodak Plus-X Pan, and Tri-X professional (320) Camera: Toyo (Omega) 45d with Fuji Fujinon 250mm f6.3 and Caltar IIn (Rodenstock Sironar N) 150mm f5.6 Scanner: Epson V700 All in all, I was quite happy with the results.

A little bit of ORWO history- Germany's big photo film/paper manufacturer up until Germany's losing WWII was AGFA (short for  A ktien G esellschaft F ür A nilinfabrikation - or corporation for some sort of plastic manufacture.) Germany was occupied by the winning powers USSR/USA/GB/FR and the rift between the USSR led to some complications for industries. Depending on your view of history the US and western allies were much friendlier to the land they occupied (remember the USSR lost many millions of their citizens to the NAZIs which made them much less tolerant.) In any case, some factories in the east moved to the west with many key employees. Most photo enthusiasts know of the t
