If the Sunny 16 rule is F16 at 1/film speed ( in this case 1/1600 of a second) F1 is effectively 8 stops faster thank F16..... Going top 1/15 of a second is 7 stops more light.... a total of 15 zones darker than daylight........ You can take a picture at F1 in basically darkens at 1/1000 of a second ( 8 stops) . When in heaven's name would you use 1/15 of a second, an additional 7 zones ? A better question is how do you focus the camera in such dark light? Or do you let your negatives get more dense as light changes? Frank Filippone red735i@earthlink.net First, I start with the Rabiner Neopan 1600 film/developer solution. Then, with the Noct at f/1.0, I have latitude in shutter speed choices. Sure, it's cheating. I'll sometimes venture to 1/15th second, hoping for a zen-like, semi-comatose state while the shutter is open. Fat chance.
