Art,
Each element is normalized so they all deliver the same data. Not rocket
science but tricky. We just do a better job at it.

This may be two different systems at work. The Nikon uses a CCD with no
color filters on it, changing the color via the changes in light source
color. Therefore, I believe Nikon scans three lines of info of one color
at a time (in the three line mode). However, the Polaroid uses a CCD
with colored filters on each line, (R, G and B), so it only scans one
line per color, and each sensor line is individually calibrated, in
effect making those 30,000 calibrations.
