Since removing the input and output DRTs from all the RCM project settings in our Monster guide (Dolby Vision says to set them to ‘none’), we were sort of at a loss as to what to do, since we learned from Cullen Kelly how critical it is to keep 18% gray where it belongs – and just adding a curve by ‘feel’ was not going to achieve that goal. Fortunately, Phil Holland’s philmColor R3 LUT pack comes with a dozen curves, all of which maintain the black point of log3G10 and keep 18% gray precisely where it should stay.

Cullen’s free DCTL exposure plugin for Resolve does this for you perfectly for a variety of tone curves.
