Hello Thomas, Roberto Fiandri turned me on to this site which I think has what you're looking for:(posted 8847 days ago)Personally, I'd rather enjoy (!) the grain of HIE than put up with these kinds of ASA/ISO numbers. One of the nice things about 35mm is it's made to be hand held. I always feel like I'm working in the wrong format when I put that little thing on a tripod (this is sort of a joke). Seriously, I'd rather load up 4x5 hie than mess with the roll film Konica, which never delivers the goods, even through an 87c at asa 6. Good luck with the Maco film... t
