Dick,
It is in how they see the light that these digital cameras back differ. They
just don't capture the light "raw". All CCD photocells inside these have a
personality of their own in the form a spectral sensitivity curves imparted
by the manufacturers. Just like ordinary desktop or hi-end scanners have. It
is usually done through the use of filters in front of the CCD to modify its
raw behavior.
