I am using RT 4.2 on Ubuntu / Linux and I shot in RAW with a Canon 60D.
I took a picture with a white background , but the raw file has a bit of a blue tint off white on the white background.
I thought I could fix this by just clicking on the spot white balance pipette, but when I do this it appears to have no effect.
If I save the file as a jpeg and then edit in GIMP, the equivalent tool …colours / levels / pick white balance with a pipette works fine.
Am I missing a trick, what am I doing wrong ?
Regards
Phil
