Portra 400. I shot 10 rolls two week ago, shot them as 200-1600 and can't tell which is which. It really is that good. Which can also be very beneficial when you're underwater and realise that you need 200 for this shot and 800 for the next one. It is also very scanner friendly, if you scan yourself.
So i would be able to shoot different speed on the same roll and it will come out ok? Thats great
