Originally posted by Oakland Rob I notice that whenever I choose "auto" in Lr it shifts everything to a warmer level, especially in these desert shots.
I think this happens pretty much always with LR. I don't like its AWB.
Originally posted by Oakland Rob Or, instead of using "auto," should I use something like the clouds for a neutral to measure? I'm not sure how much I could trust that, but we're talking post processing here where my eye, "auto," a custom measurement and the preset I shot at home with the Passport are all compromises.
I would say just use Daylight WB. Using the in-camera set custom WB option is only good if you have a greycard with you and know how to use it.
Originally posted by Oakland Rob I happened to be looking at shots in woodlands/greenery near home at the same time as the shots in the open desert, and the camera's "as shot" using the AWB seemed to be very different based on the terrain, not the sun or clouds. I would have thought that wouldn't have mattered as much (and I'm assuming "as shot" in Lr means it uses the AWB parameters).
AWB just analyzes the colours in the photo and tries to guess what would look natural, good. Different cameras and software use different algorithms to figure this out.
But I suspect the problem isn't just WB. Could you maybe post a sample photo, with the original WB?
Why I think you have another problem is because you are mentioning colour passport, which is actually a camera colour calibration tool, and not a WB tool, if I remember right. There is a difference between those two, and if you have a weird camera colour palette, then WB won't be able to fix things
Other things I like to do in such cases is to use Split Toning to add some colour cast in the highlights or shadows, whichever needs it to make the whole scene seem more normal.
