"Advances" are often just a different set of trade-offs,
with (sometimes) a bit of advantage added...;-) In the
case of the TRV30, my guess is that using a megapixel
CCD without a CCD design change would have resulted in
unacceptable low light performance (and older CCD designs
in single-chippers showed noticeable color failures,
especially in greens). Along comes a Sony "HAD" CCD, with
greater sensitivity, and better color - but it has a
"price": very bright areas in darker backgrounds "propagate"
in the CCD image vertically. So we have a one-chip camera
with the megapixel gain of increased resolution, excellent
color rendition (for a one-chipper), and acceptable low-
light performance for a one-chipper with a small CCD and
really tiny pixel-size... The price of this design is the
occasional problem with bright areas in the picture (plus
the usual 1-chipper sharp-picture "busy" look along scan
lines with motion). Understanding this, you make your
choice of camcorder depending on what image characteristics
are most important to you... As for the TRV30 and others
with the "HAD" chips, a good shade helps - but only when
the bright area is outside the picture area.
