Great topic with some useful tips. I basically followed the advice that's on the training videos on this website. Add volume to the highlights. This simulates the clear base layer of celluloid film on a positive print that used to be used to project films. Luma curve to bring really high highlights into range with the rest of the shot and to flatten them out so the transition is smoother. Most important on really dark scenes with exposed light sources. Tone curve, which is mentioned here a lot. Roll off the highs and compress the lows a bit. These techniques are all simulating the way actual film behaves. I do a lot of colour darkroom printing from negative film and also use printer lights there so they make sense to me in Resolve for the actual balancing too. All colour goes at the start of this chain. This is all on log footage. Then key or mask out coloured objects that upset the harmony of the shot and bring in power windows to focus the attention a little or create light level variation if the shot is a bit flat.
