That is unfortunately true, as the last image on the wiki page would
suggest, but it still doesn't cut off all IR radiation. Even modern
DSLR cameras come with the IR-cut filter right in front of the sensor,
but cranking up the ISO and blocking the visible spectrum can still
result in some nice IR images (with whatever little IR that passes
through).

If someone can get the night mode on the camera to work, it might turn
out to be an interesting experiment ;-)
