My interest in photography is more toward it's creative aspects as opposed
to the engineering details of the equipment/software. But with that said
my
impression, and it is an impression only, is that for years the CCD sensor
was the higher quality, more expensive sensor, but along the way the
sensor
makers were able to improve the CMOS sensor to the point that it may
become
the present day standard from a quality/$$$ standpoint. I have Nikon and
Canon DSLR's that have both sensors and from my standpoint there isn't a
gnat's eyelash of difference between the two in the end result. But then
I'm not picky in that regard.
