How does Lightroom associate a preset with a camera profile? Is this the UUID in the preset's .xmp file? If so, how/where is this associated with the .dcp file?
The underlying issue I'm trying to address is taking some of my existing camera-specific presets that I've purchased, and making my own tweaks to them for different camera systems that I own. I understand how the edit the dcp files; I just can't figure out where the connection between the xmp and dcp file is taking place.
