Chuck Westfall's answer is probably technically correct but doesn't 
really address the issue or raw mode vs. JPEG.  JPEG's only have 8 bits 
whereas raw mode images are typically 10 or 12 bits.  Now it could be 
that he's saying a 2 micron pixel can't distinguish any more than 256 
brightness levels but it that's really true then they probably shouldn't 
have produced a 2 micron pixel in the first place.  In either case I 
guess we don't want a G7.
