Hello all!
I've been struggling twice so far to obtain the so called UniWB
on a Pentax K-30, but without any real success so far.
Has anyone been able to succeed at this? (And maybe share a raw
photo that has the appropriate WB settings?)
I've tried the method described on

When you view the histogram on your camera, the histogram is based on
the JPEG rendering of the photo, even if you're shooting raw. That
means that the R,G,B channels shift relative to each other based on
the white balance setting, the saturation point changes based on the
contrast, etc., even

UniWB, as I understand it, is an effort to find a set of camera
