That one is easy, Shel, each bit doubles (or halves if you are going that way)
the dynamic range of the image. Powers of two, you will recall.

The D and the Ds have 12-bit sensors and, through the magic of some
algorithms or whatnot, by the time the images are converted to a RAW file,
they are considered 16-bit files. Some cameras have 14-bit sensors. What
kind of improvement might one see when using a camera with a 14-bit sensor
compared to one with a 12-bit sensor, all else being equal. I have heard
that dynamic range is improved, i.e., more shadow detail is available and
highlights don't fry as easily with more bits in the sensor. Of course, all
else isn't usually equal, so what other factors play significant role in
determining image quality, apart from lenses.
It's also been stated that some cameras use a "lossy" system when
converting to RAW output, others a lossless system. Which type does Pentax
use, and does it really matter anyway?
