folks, I think I read some time back, probably on Pixls, that it’s better to do the white balancing along with the demosaicing, rather than afterwards. If you want the best quality then, perhaps one should use DCRAW and input the factors. But how do you know what they are? Can you use RT to set the white balance wysiwyg, and somehow obtain the factors represented by the temp. and tint? I can’t see an obvious place where this is. Looking at the exif in a jpeg produced by RT, there is “ColourBalance” at “10, 798, 1024, 1024…” and MeasuredColour at “12, 442, 1024, 1024…” but these don’t mean much to me and when I expand the pane, the "…"s remain.
@Elle, I’m confused when you say
Why would you do this, wouldn’t you produce a green image? - but I might be confused!
Surely one would use the appropriate factors for the interpolating/demosaicing, not (1,1,1,1) ?
