I have shot a roll of 120 Fuji Acros 100 at night. Times are between 15 to 120 seconds. What type of development do advice for this? Should I follow recommended time or is this a push-development?
I have XTol, Rodinal and HC-110 available. Which one would be "best"?
Have not taken any night pictures with Acros before and could use some guidance.
I don't do anything different to pictures exposed at night.
Bright lights, if there are any, will look really bright, but if you compensate for that relative over-exposure, the rest of the tone-scale can look really weird.
I generally process night-shots as normal. Acros is pretty low in contrast already and has no reciprocity failure for the times you listed, so it deals with night shots very well. I reckon it looks nice in D-76 (1+1 for 11:00) and in Rodinal (1+50 for 13:30); I haven't tried XTOL but I'm sure it would be fine.
If your dynamic range is huge, you can do a 1+100 semi-stand in Rodinal (the 18-minute thing in MDC) to bring up the shadows but I find (with 500mL in my tank) that that can lead to dead-looking highlights because 5mL of Rodinal isn't enough for one roll. XTOL is probably better for bringing up shadows.
Given that the dynamic range is usually pretty high with lights or harsh moon-shadows at night, you almost certainly don't want to push.
