Time for Efke R25 in Rodinal

Discussion in 'Black and White' started by martin_pistor, Nov 5, 2002.

  1. 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.
     
  2. Try Rodinal (1:100) for 9 minutes at 68 degrees.
     
  3. For 1+50, their sheet indicates 4.5 minutes at 68F. Prewet 1 minute in water, agitate 30 sec then every 15 sec. (1+25 is 5 min).
