Originally posted by GabrielFFontes My K-30's AWB is pretty consistent, just checked some raws, and the color temperature doesn't seem to change a lot between shots of the same scene.
That's my gripe with AWB: ideally, if the light source hasn't changed (e.g., sun), the camera shouldn't change the color temperature
at all. In practice, the camera will change the temperature whether the subject is the sky, grass or a brick wall, even though everything is under sunlight (6500k).
Hence, when you fine tune, you're just offsetting the error instead of fixing, because AWB changes the base temperature all the time. Using AWB and trying to fix in post is also a pain, because each shot will have a different setting, so you can't adjust an entire set based on a sample shot of a grey subject or whatever, even if the variation is small (because an adjustment will make one shot perfect, but ruin the skin tones on another).
I prefer the camera to handle white balance like negative film did, having a
consistent (rather than
possibly right) temperature for an entire set, so you have latitude to work on post.
