Although I can't answer your specific questions, be aware that Acros is a rather "hot" film; that is, through most of the usable range the curve shape is straight but then it bends _upwards_ at the high end. This can make some bright highlights that print as blank white without quite a bit of burning when you print them. I've not yet found a developer that changes the curve shape.(posted 8058 days ago)Also...beware that the "real" speed of Acros is usually found to be around EI 50-64.
As an EI 64 film with lots of "zip" it's good stuff if that's what you want.
