Actually, this is nothing but a grain test. I found some 35mm Aerecon Plus X on the bay and thought I'd check for film base plus fog. It's stunning film. Clean as a whistle. Since I had no set development time I thought I'd be crazy and try a few new things. This is Dektol, 1 gram / 100ml / 1shot. That's roughly 1:10. I simply aggitated for 1 minute continuous then let stand for the remainder of 32 minutes.
I got lucky, there's no other explanation. Grain is zilch which is saying something for Plus X. Gamma is as close to perfect as I've ever seen.
Maybe I should hit the slots tonight.
