"Carlotta’s encodes were terrible with heavy blocking in the highlights and pervasive chroma noise. Criterion / NexSpec did much better and only occasionally struggles with skies. Grain is finely detailed and it doesn’t look filtered. Grading is debatable and particularly whether all three subsequent films (shot years apart by two cinematographers, one of them being the legendary Néstor Almendros) have roughly the same visual identity. Still, colors are adequately balanced with variations in the (yellowish) hues, there are no tints, black levels and shadow detail is excellent."
