I've got some Foma 200 coming in 4x5 and 8x10. I plan to use it mainly for portraiture. Should be fun.

Just ran some quick zone tests on Foma 200. My N EI is 160. Rating it at 800 and extending development gave very good results. I used DS10 1+1. N development at 75 F in Jobo Expert Drum at rotation 3 was 8 minutes. EI 800 was 17.5 minutes. The film looked fine, with no defects to the eye. It dried flat.

An experiment: a post-office red post box (what other colour could it be) in a whitewashed wall, close to noon - with a film that cuts off deep red at 650nm. I expected something quite contrasty.
Fomopan 100 exposed at 80, reflectively metered off the back of my hand - which turned out pretty much sunny-16 as expected, developed in RO-9 for nine minutes at 20C. Scanned negative.

Got my box of Foma 200 8x10 sheet film and am questioning the reciprocity correction recommended on the Foma website. Has anyone checked this films reciprocity correction to ascertain its operating validity yet? Thanks!
Hard to say. But at three stops correction for only a 10 sec exposure, at least their spec sheet makes it obvious that the long exposure characteristics of Foma 200 are horrible, which many of us already realized from the school of hard knocks. What bothers me is that they state this with respect to box speed, and this film is nowhere near that in real world speed. You might want to rate it more around 100 and then apply the 1.5 EV correction for 1 sec, and at least double at 10sec. Personal testing is important. I tried my best to avoid anything longer than 1 sec. You don't need to overexpose for shadow values. This film has an exceptionally long straight line and will resolve shadow detail quite deeply if you rate it at 100 and place shadow texture threshold down around Zone I. This morning I was looking at one of my extreme contrast range prints successfully made from this film without resorting to any kind of weird developer. It does develop especially fast, so you have to watch out for that idiosyncrasy too to prevent excess density.
This seems to be the best info I could find on the web. I haven't confirmed it yet.
