The question really outstanding for me is that in the past most times… i see that as shot legacy is very very close if not visually identical to D65 legacy + CC set to as shot… In this case it was not. It seems to be amplified by the wrong WP being used by DT when using the modern WB.
Does the legacy WB clip some how so that the values extending beyond what should be white if the correct WP was used aren’t so apparent??
