After buying a few rolls of this film and the Silvermax developer to develop it in for full effect, I have concluded that even processed normally, this film is bette suited to be shot at 200 ISO, possibly 400. With a tiny push, 800 is definitely possible for a very full range. An exposure test at 800, 400, 200, and 100 EI on the same roll processed as 100, (11 min 68F, 1 + 29) the 800 had the best tone separation. I found 100 to block up the highlights too much for my normal sun exposure I use with Tri-x (1/1000 at f-8 ISO 800 or 1/1000 f2.8 @100 in this case). The shadows have the best range at 100, but at 400 the highlights work the best. Ive attached a few examples. The last two examples of the stop sign in the alleyway are shot at 800 (100022) and 100 (100025). The rest are shot 1/1000 f2.8 in the sun.
