I was just playing with my new Nikon D200 and discovered something that surprised me. Unless there is some quality adjustment setting I missed, it's color bit depth apparently is only 8 bits in NEF Raw. By comparison, my Polaroid SprintScan 4000 scanner has a color bit depth of 12 bits, and other scanners have much higher color bit depths than this. While color bit depth is a commonly cited specification for scanners, I've seldom seen it cited for digital cameras. Does the lower bit depth for the D200 imply lower quality color rendition than my 12 bit scanner? <<<<<<<<<<<<<<<<<<<<<<<<<< I suspect you've done something wrong. This reference http://www.clarkvision.com/imagedetail/digital.sensor.performance.summary/index.html Shows the D200 doing very well indeed at ISO 100. I'm quite sure it uses a 12-bit A/D converter. Note that just because a camera or scanner has X bits in its A/D converter doesn't mean you have X bits of valid data in the output files. David J.
