Ted Witcher said:Not to hijack, but how does one calculate the time necessary for those deep-stop night exteriors? They look amazing. What's your technique? Just "B" and a stopwatch?
Thanks for the nice comment on the images Ted. I use B and a Casio watch with count-down stop-watch function for timing. As for calculating the right exposure time it's come from experience mostly and gut feeling. I learned in a night shooting seminar up at Mono Lake that out in the dark late in a forest on a moonlit night that f/5.6 or f/8 for about 13-18 minutes works well for Acros. For the city shots and similarly lit areas (old bases, industrial areas, etc.) I found that typically f/5.6 and about 4-6 minutes works and I use my gut feeling to adjust up or down slightly based on how much security flood lights might be spilling some light into the photo, or how much the sky might be lit by light pollution, how much misty cloud cover might be in the sky, and so forth. But really with not only it's great reciprocity characteristics Acros also has some very good latitude which helps too. I suggest if you try similar city night scenes try f/5.6 and 5 minutes and see what you get. Or better bracket by a minute or two either way and then see how dense your negs are. I personally find a slightly less exposed and less dense neg is best for my workflow of scanning and working in PS. Let me know how it goes....
Now all this said I've also had good results using Neopan 1600 shot at 1600 and developed in D-76, all shot at 1/30 and 1/60 at f/2 and 2.8 hand-held with my Contax G2. It was a rainy, wet night though which is a bit brighter than typical for night. Different style of shooting but it works too! See this tagged set (click on thumbs for larger image views):
