In Resolve is do use L*a*b to grade, i've had enough seat time with client attended sessions to feel comfortable with it, and in Resolve find i can get to a decent base grade quickly withe these tools
I'm not sure the RLAB in Baselight and the L*a*b in Resolve are the same, likely the conversions are not, and the feedback is not quite the same, not better or worse, just seems to be not the same
but i'll need to test properly, or wait for v5 and Basegrade that seemingly takes some cues from L*a*b's non-linear responce that mimic's the way the eye sees colors
