I'd be interested to know that too. If you take the attached reference clip and look at it on the vector scope, he get a very narrow scope which seems desaturated because the colours seem to compressed but image feels so rich. Is he desaturating the image first then saturating specific narrow Hues? Am I making sense in what I'm trying to say? Also, when you say he keeps it simple with few nodes, is he doing multiple corrections within a node? Eg, log tools, hue vs hue, hue vs sat etc. Has Stefan or any of the other guys at CO3 (like you Tom) considered making a Masterclass on grading?
