Expect an incredibly sharp negative, with grain. HP5 grain is not bad though, kinda clean looking.
Very good tonality and if you overagitate you may blow the highlights.
With Rodinal 1+50 I've found that it's best to agitate only once/minute

From what I've read, Rodinol is used primarily with finer grained slow films to give very good sharpness. Of course I will "try it and see", but I was just wondering if anyone else uses or has used this combination of developer and film, and what kind of results they got with it. My next roll of 120 HP5+ is going into the Rodinol so I will see for myself, but I'm just curious about what to expect. Can anyone help?
