I have shot this film in 120 and 4x5. On my first trip out with it, shot at the box speed. Not happy with the results, Low contrast (thin) negatives. Second trip shot at 160, slight underdevelopment. Too grainy and crappy highlights. Still too thin. Not happy... All processed in D76, 1:1.
Mistake on the third trip out. Thought I was shooting a Grafmatic full of FP4. Usually shoot that at 100. It was the Bergger. Made an adjustment in the developing time to 8.5 minutes @ 68F, ID-11 stock solution. 1 minute prewash/soak, and development in a CombiPlan tank. Initial agitation 30 seconds, three gentle inversions per minute. Result: a fine negative! I have read later where others routinely shoot this film at this speed.
Some will compare the BPF 200 to JandC Classic 200. While it may be made in the same plant, it sure aint the same film. The Classic behaves well at the 160-180 range, and delivers a spectacular 4x5 negative in a wide variety of developers.
