Thanks for viewing and comment --- well, I rated film at 500 ASA because it was so outdated and with some other P3200 i used it gave good results BUT this batch seems to need even more exposure. I just set the 500ASA on the exposure meter and either use an 'Incident Light Reading' with the Weston Invercone OR use a Reflected light reading off the stone pavement or road surface. ( The KONICA Auto-Reflex TC I used had NO bateries as it took 2 of the now-illegal MERCURY 1.35 Volt types so I used a Weston Master V British Meter).
It was found even when FRESH that Kodak P3200 was not up to 'box speed' same as when Kodak brought out the 'new' Vericolor 160 for weddings -- I rated it at 125 ASA.
i was n ot striving for 'grain' as I knew it would be grainy -- just to use up some of that old film in my fridge with the Konica camera I had not used for a while.

It looks a little grainy, which is maybe what you were striving for. Am I correct to say that Kodak did not rate their P3200 but most users rated it at 800? Why did you rate it at 500?

I'm still sitting on the fence debating if I should get a Leica M7. I am going to get a Canon M5 and adapt onto it a Leica 18/3.8, a Zeiss ZM 35/1.4, and the Zeiss ZM 50/2. (Yes, the Canon is under-kill but I suspect that will change in time and I'll just invest in the lenses now and buy better Canon Mirrorless bodies when they become available.) The M7 is going back to when I fell in love with photography many years ago but never had the resources to dive in. My debate is should I spend on film. Everything is still available, for now (chemicals, film, film scanners, etc.) Thus I now need to relearn ASA/ISO.

How do you rate a speed yourself? Is it not inherent in the film at production?
