["Norman Unsworth" <unsworth_norman@aclink.org>]

How do the bad elements in the CCD evidence themselves?

I recently had my Minolta Dual II replaced by Minolta, after only owning
it a week.  The second one has lower "noise" in the shadow areas than
the first... 

More important, however, is my first one had many "bad" elements in the
CCD.  I was unable to determine if this is a matter of physically bad
CCD elements or dirt in the unit, or defective filters over the CCD, or
bad calibration or what.  The first unit had between 3 and 5 bad sensors
per color...
