Starting from the camera setting for white balance, RT gives some files very high temps, 40000K or 50000K. The same file opened in other raw developers might come out at 8000K. Casual observation suggests this happens when the sky is blown, for example. A change from Camera WB to Auto will sometimes bring the temp to a reasonable value.
Why is RT so different with some cameras? I’ve seen this on Sony and on Leica SL. Very high temps are not meaningful to me and therefore difficult to adjust to taste.
