I have one of these, and it takes rather nice B&W infrared video
(white clouds, black sky, white foliage) during the daytime (when
in night-shooting mode and with the B&W picture effect engaged).
The effect can be enhanced by adding a red filter (and a polarizer,
for darker skies and/or for modifying water and other reflections).
I did notice that the open-weave cloth on my stereo speakers
became nearly invisible when using the IR mode, but the
implications didn't dawn on me until I saw this article...;-) After
hearing about this "see-through" effect, for the heck of it, I went
downtown yesterday and videoed people with the Sony TRV-9
camcorder with the "night-shot" IR mode on, in B&W mode, and
with red and polarizing filters on the lens. Not surprisingly, there
was nothing unusual visible (beyond the rather nice effects of
B&W IR shooting...). Since this camcorder can shoot through
black speaker grille cloth, I suspect the "see-through" effect
requires that the cloth have a very open weave, and possibly
also a dark color - not a common occurance...
My guess is that Sony has found an original way of clearing
out its old stock of a camcorder...;-)
