I'm leaving for France on Sunday and have a question about using Efke 100 in very low light. I rate it at 50 for bright days, but I will be photographing the Black Madonnas in dimly lit crypts as well as the landscape. I've heard that it's best to rate it at 100 for low light and that the reciprocity factor is basically the same as Bergger 200. The chart for this is on the AZO forum. Is that accurate information? Efke is fairly new to me and I will be travelling with my standard Tri-x, but I want to use both. I'm working in 8x10 and contacting on AZO. Any sugestions would be appreciated.
Thank you.
