I have recently tried the Polapan 55 pn. Great film! The problem of getting the right exposure is discussed here in several Q&As. I have had some good results exposing at ISO 32 and only compensating for bellows extension. I normally use a 500w tungsten lamp.
However, when it comes to longer exposures, the outcome varies, and I wonder if anybody can give some ideas about how too compensate the reciprocity? Thanks in advan
