I already found some information searching the forum, but this particular combination wasn`t mentioned. Has anybody of you experiences with the Efke R25 in Rodinal 1+50? It would cut down the testing range (not really making testing unnecessary). The goal should be a pronounced (sharp, not necessarily large) grain with a medium to low gamma (negs in ID11 became still really hard printing on grade 0). Shooting 6x6 and 6x9 the loss in finegrain is rather wanted. I expect the emulsion still to have a finer grain then the R100.
