>>3683113And here's some Portra 400 @ 3200, colours turn really warm w/ minimal grain increase
>>3683082Haven't shot Portra 800 but I'd say that I'd probably push better to super high speeds, as Kodak markets it as being able to push to 3200.
Control F "Characteristic Curves" on the Portra 800 datasheet and you'll see a curve for EI 800, EI 1600 and EI 3200. Kodak doesn't show pushed characteristic curves for any other film stock, nor mentions pushing for other film stock on their datasheets.
