ideas? thoughts? things to check?
start with changing of camera profile selected in LR for your raws... if you do not like the results w/ other camera profiles then
1) make/save a default preset
w/ certain adjustments that you find you always do, for example in HSL tab, etc (w/ whatever camera profile selected you still find the most suitable)
2) modify camera profile (either using Adobe DNG profile editor or dump .dcp to .xml and edit baseline exposure correction, curve, remove Adobe's LUTs to make it purely matrix - you might like that better - then compile that back to .dcp = Sandy Mc made a beautiful tool for that, dcptool, google it)
3) use the dumbest way - shot some colorchecker target and create a profile from that (Adobe DNG PE will replace original LUTs while preserving the matrix part of color transform or if using XRite OEM software you might get a new matrix part too... alternatively there is a QPCard target and software)
