	One possibility that would enhance tonality in the shadows 
(somewhat at the expense of the highlights) would be that the 12-bits they 
include in the RAW file are nonlinear.  Currently, all the RAW files are 
the linear output from the sensors.  Converting these 12-bits to 
gamma-corrected would more evenly distribute the tonality among the 
highlights, mids, and shadows.  Oh, and since 8-bits gamma-correct is 
"enough" so long as things aren't post-processed, having 12-bits of gamma 
corrected gives 16x as much latitude.

	Hey... it's a possibility.
