Interesting release. It sounds like the new Portra 800 is the first of the two electon emulsion still films (like Vision 2 motion picture film). The new base is also good news. I just hope it curls a lot less than the old stuff.
I loved the fat grain of the old/current 800 film. Pulled 2-3 stops and developed within an inch of not developing anything at all produces as flat, desaturated and grainy an image as anything captured on colour film.
