Does anyone have information on Bergger BPF 200 and the reciprocity numbers for this film? Great forum. Thanks in advance.

You can email them at:" email@example.com " and they will send you the data sheet for the film. My copy isn't handy or I'd just answer you... But the reciprocity curve, as I recall, is nearly a straight line and easy to calculate.

Two stops always seems to be right for your average B&W film. I would start there.-J
