If you thought that adjusting simple things such as exposure, contrast or playing with curves would really behave in similar manner across different NLEs, well guess again. I always thought that yellowish-greenish dark skin tones & magenta bright skin tones were (yet) another Sony quirk. Interestingly the image out of the camera was fine but as soon as I made a change in the Lumetri panel, skin would turn into this deadly color. So while I was about to create an LUT to fix them I tested Resolve and FCPX and lo and behold I could not reproduce these awful tones! What’s the deal then? After testing extensively these programs I found out that all three behave differently! Resolve: gain changes all three channels with the same multiplicative factor. While that creates nice desaturated shadows, skin highlights have a problem since the red channel clips first and then green follows creating these yellowish hues. FCPX: exposure is just an additive term on all three channels, so wh
