One of the beautiful things about this module, is on majority of images, you don’t have to know anything to get great results. In settings, processing, make sure auto apply chromatic adaptation defaults is set to ‘modern’. Then reset white balance (it should be ‘camera reference’ giving 1 tint, 6502 temp), and CAT part of chromatic adaptation will automatically give great results. Linear bradford is suitable in majority of circumstances (daylight, tungsten), so you just move on without even thinking about it. There are a few if this, then that scenarios. Here is my list:
*If LED’s or coloured lights are in shot, use cat16. Other weird scenarios like mixed lighting may also call for this.
*If you want to temper sunsets, but retain blues, try non-linear bradford.
*If cct says invalid, use custom hue/chroma, or the colour dropper (which adjusts the hue/chroma). When using colour dropper, draw a square around an area which should be neutral.
*use gamut compression if lots of colours are OOG. Use clipping indicators to check this, with softproof profile = working profile (for master edit).
There is a lot more can be done, but that is my starting point. It only seems to really break if your camera has weird coefficients. Aurelien tells you how to deal with this in the video, from about 52 min mark. The other part of color calibration is the channel mixer, which a lot of people don’t understand anyway. But ‘colourfulness’ (similar to saturation) and ‘brightness’ tabs should be pretty intuitive for most users.
