Thanks, Bob... I'll use Acros as I've used APX100 for years: under direct sun only. I shoot ISO 100 for rich shadows at 1/125 f/8 (with yellow filter). I also use it for selective focus at f/1.4 and high shutter speeds with an ND8. For lower contrast scenes I use Tri-X, and for low light TMZ... One body for each film. I've heard lots of great things about Acros in Rodinal... I know it's modern grained... I'd better like it, because 40 sunny rolls will last more than a year: I shoot a lot more ISO 400, and lately, even more 3200 to stop down and get grain...
Cheers,
Juan
