While reading Michael Reichmann's impressions of the Leica M Monochrom
Camera on the Luminous-Landscape
<http://www.luminous-landscape.com/reviews/cameras/leica_m9_monochrom.shtml>
I stumbled across this interesting bit.

While discussing the camera's ability to display a histogram based on
the raw image data rather than the embedded jpg he says:

"This has not been possible till now because with the raw file from a
colour capable sensor the white balance is indeterminate. Depending on
how the raw file is subsequently processed one or more of the colour
channels might be blown. But because the MM has no white balance a
true raw histogram display is possible."

I've seen the histogram change as a result of changing white balance
when I'm in Photoshop or Lightroom. So, if the histogram in the camera
is based on the embedded jpg, it makes sense that you would get a
different histogram with different white balance settings.  That
probably implies that if you use the histogram you'll get marginally
better results if you set the desired white balance in camera while
you shoot.  Things like those goofy picture styles probably make a
difference too.  They alter contrast and other settings to get
different jpg renderings.

I'm not sure if the differences will be big enough to matter, but if
you're a pixel peeper it will give you something more to be worried
about.

Food for thought.
