    Acros 100 (120) Reciprocity Question

    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.

    Though I do not know the exact limit of Acros, I have read many places about it's amazing reciprocity characteristics.

    I'm a fairly new to Fuji Acros 120 and got some for a trip because I anticipated shooting in dim light and it's pretty amazing with long exposures. Here's a chart I found.

    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.

    Technology is not a panacea. It alone will not move your art forward. Only through developing your own aesthetic - free from the tools that create it - can you find new dimension to your work.

    Thanks for the responses all. I love this film and can't wait to try long exposures with it.

    I can attest to its amazing reciprocity. Feel free to review some recent work with Acros under moonlight and astrophotography. No other B&W film can match the characteristics of Acros in pure recording power under low light conditions.

    I can see. Great job. I've always hated reciprocity failure with film. I get empty shadows and highlights blown out on my negs. Fuji Acros seems to have less of a problem. I've tried to tackle this problem with other films with stand development.

    Amazing stuff there, Mister Fly. You got that dialed in pretty tight.

    I did a series of shots with moonlight where I didn't adjust for reciprocity. Looking at the negs laid out, anything past 6 minutes needs to be extended by 25%, but beyond that, I didn't shoot on the roll.
