[Leica] M9 color balance

[hopsternew at gmail.com (Geoff Hopkinson)]

And to expand on what Leo has said there, the white balance is not set in
the DNG, except as a note in the EXIF.
That is to say your camera's setting there have no effect whatsoever on what
is recorded in the DNG.
The low resolution preview for your LCD (subject to how that is adjusted) is
intended to show you what a default JPG setting conversion may give you
though
Your in-camera setting can certainly be used as a starting point when you
import your files with your Raw converter.

Also of course what you see (as preview) on your computer screen after
processing by your Raw converter will be dependent on its settings too.

In the case of the M9 there is some lens dependent processing in camera due
to the nature of the sensor (eg. for vignetting) and the actual recorded
data has to be corrected quite a bit to produce a homogoneous, symmetrical
output at all.  Nevertheless your in-camera WB is irrelevant as far as
actual data recorded.
I am speaking of course only of DNG files with the M9.

Cheers
Geoff
