Hey guys!
Looking for White Balance values aka. "ColorBalance1", "RedBalance", "WhiteBalance" in a DNG file, produced by Pentax K-30 - however, I cannot find something like that? Was it maybe renamed?
I am trying to grab the values for this: http://www.darktable.org/2012/10/whats-involved-with-adding-support-for-new-cameras/ - Section: White Balance Presets

Does this give you what you want?:
White Balance : Daylight
WB RGGB Levels Daylight : 18129 8192 8192 13346
So
Red Balance = 18129/8192
Blue Balance = 13346/8192

Thanks a lot! Exactly what I was looking for.
cheers
I'll consider adding a new Composite tag to allow these to be calculated automatically.
