Description

The raw.pixls.us/Canon/EOS 5D Mark IV/B13A0800.CR2 sample.
Image is all right, but the wb provided by rawspeed is wrong.
If i manually select (1,1,1) as wb, image looks right.

Compare the provided white balance with the manually selected (1,1,1) result; the issue is done when this sample renders with the correct white balance.
