I'm trying to understand the path that a RAW image takes into Lightroom/ACR.
Does the image pass through the camera profile (Adobe Color for Nikon D850) into the Profile Conversion Space (L*a*b*) then from the PCS to Lightroom/ACR Prophoto?
Or is Lightroom/ACR Prophoto part of the camera profile?
What role does the PCS play, in other words?
