I have been an avid shooter of Acros 100 for several years, and plan on doing some long exposure photography soon. My experience with films like Kodak TMax is that you have to adjust the exposure times for 2 seconds or more; however, in reading the data specs on Acros 120, it appears that no adjustments are necessary for exposures longer than 120 seconds. This seems to be an extremely long time, can this be true, and does anyone have any experience with long exposures with this film that can give any further insight? Thanks in advance.
That is correct. It's an amazing film.
Do remember however that all black and white films can more easily be corrected for in the darkroom with over as opposed to under exposure.
