Response to pmk and berrger sheet film

Two important things: First, Bergger BPF 200 is EI:100 and will not have enough shadow detail when exposed at 200. Second, Jobo and PMK are NOT compatible. Some Jobo users are using a different pyro formula called 'rollo pyro.' Make no mistake; this is NOT PMK and you must not expect the same results as with PMK. As good as the JOBO system is, it simply cannot be used in all situations. I suggest that you learn how to develop sheet film in trays. With a little practice, you can get perfectly even development and no scratches. Ansel Adams' "The Negative" has very good illustrated instructions on tray development. Normal development time is 14 min @68F for film exposed at EI:100.
