On the Mavic, this is not the preview in the raws that sucks, this is the embedded JPG processing itself that sucks.
Yes, I tried with dual lum profile, but this just does not work for complex subjects, or I would have to reshoot a color checker every 100 pictures and that would become a nightmare because I would spend too much time editing the raws…
Take for exemple a building - with the sun, at say 4 or 5PM that gives you at least 3 different lightings (if not more) for the 4 faces, from direct sunlight (exposed side) to indirect and total shade (opposite side)… So for this kind of subject we could shoot 3 sets with 3 color calibrations, but of course you have issues at overlaps…
And of course sometimes you want these changes, because lighting is part of the subject : you can not always try to get the reflected ideal color of your subject only (even if we could).
Ideally I would see that as part of the workflow in RC (I could maybe turn this into a feature request) :
-work with the RAWs, so no information lost (12 bits-14 bits + EXIF that gives RC informations about exposure…).
-align the pictures.
-for outdoor given the time of day / GPS position, RC can compute a light model of where the sun is, the user would just have to say how cloudy it was that day.
-at texturing, all these informations are used to compute texturing given the user’s choice :
-remove the illuminant (so try to balance every picture) or not
-get a constant exposure (so dark areas would be maybe all dark and bright areas all white) or normalise the exposure (what a camera is usually doing by setting exposure)
Really, this would be so great to have this handled in RC !!!
