Has any one developed berggers film in pmk in a jobo? I would like to know where to start with development time (shot at 200) and if there has been any problems I should look out for.

The Jobo web site has some information on a special pyro formula that was created specifically for use with their processing tubes. It is called Rollo Pyro. I recall that the Berrger film is one they tested with.

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.

I developed APX100 in Jobo but used hand inversion agitation with 1.4 litre of developer. No problems. I used the times listed in Anchell's Film Developer Cookbood.

I use the 2 reel tank but with only the lower reel loaded. It allows for complete intermixing of the developer during agitation.
