The source said 80 lines/mm, however, Forte claims that the resolving power of its film is 85 lines/mm: a discprepancy of 5 lines/mm is not one I am likely to see with or without glasses and I am not concerned by the small difference. Maybe I'm approaching my problem from the wrong direction. Let me explain why I posed this question in the first place. I ventured down this path because I am considering a switch to Efke PL 100, which is said by its manufacturer to have a resolving power of 90 lines/mm. I like BPF 200 for several reasons, but despite using it for some time, do not know its resolution rating. Comparing the resolving power of the two emulsions and evaluating my results from BPF 200 would, I reasoned, give me one indication of what to expect from PL 100 and would be a more objective and reliable indicator than looking at the results obtained from PL 100 by other photographers and posted on the internet, some of which are very impressive. My interest in completing this evaluation would not be as high were not for the fact that PL 100 is considerably more expensive than BPF 200. 25 sheets of 8x10 BPF 200 is $60 at Bostick & Sullivan, while 25 sheets of PL 100 is $109.99 at JandCPhoto. That's my story. Bergger has not yet responded to my inquiry.
