I used to think that Portra 800 was not very good, as it is much less flexible and advanced than Portra 400. But have a look at this: An Inquiry into Digital versus Film - Featuring the M10 vs M9 vs M6 M10 and M9 are terrific. But Portra 800 just shines. It's amazing. And it reminds me of Vision3 Cinestill. Perhaps it just loves environments with lots of mixed lighting. So what do you think?
