There is a hack for the hardware - but it is too risky

(if you can get to it [and back!] successfully, you can

disable the switch that forces the overexposure). I like

shooting landscapes with daylight-enabled IR capability

(for more, see the Sony TRV9 review at:

www.David-Ruether-Photography.com/camcorder-comparison.htm). As

for adding filtration to do what you want, try crossed

polarizers (linear on the outside, circular on the inside)

with a 3-stop ND added, plus a no. 87 filter in gel form

placed behind the glass filters. This works, but you

are using the lens wide-open, and with several parallel

glass surfaces (you will need a good lens shade).
