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.
Acros does keep good contrast over lengthy exposures without the shadows blocking up. Tonality can be somewhat flat in even lighting, but this can be addressed in post processing after scanning. I've used Xtol 1:1 standard development for all these images and it offers good accutance and fine grain. I'm pretty happy with the combination.
The only other films that can approach Acros in reciprocity are TMAX 100 and Delta 100. Acros has been the gold standard for night shooting for some time. It is a joy to shoot.
Thank you for the kind remarks guys. I also recommend Night Photography by Lance Keimig. Film and development choices are covered as well as exposure. A brief history of night photography highlights the books opening. Many examples of photography with Acros are covered.
Not noting on long exposure, But Acros is one amazing film. I/m not a fan of t grain films but there is something about Acros. One of my 3 images that I've ever made, that I would call my best work was shot on Acros. I has such a beautiful curve and smoothness to it.
Acros is unsurpassed for night shooting. I've used it extensively and have attended workshops with the above-mentioned Lance Kemig. Great guy, great knowledge. Most of my shots are done for about 5-10 minutes at f/5,6 depending on how much ambient light there is.
Here's a few examples of my work with Acros at night:
Each of these is a sixteen-minute exposure on Acros at f/16, one night away from the full moon; the first two are 645, the second two are 6x7. I noticed very little effect from reciprocity failure in any of them.
