I looked at the Q&A for Portra 160 and judging by the scales it is even closer to 160NC than the new 400 is to 400NC. In fact, the only difference seems to be grain which is now finer (a moot point for me - I never see the grain on 100 speed films anyway). I printed another 400 Portra neg last night and got a really nice print. This was a photograph of elderly relatives and it did a good job of toning down the various blotches and ruddy marks that people get as they get close to 100.
