However, I feel that I should ask whether you know that your
sensor and camera system is actually *sensitive* in the IR. I know that
on early digital conversions to SLRs, it was necessary to put a filter
on the lens to block the IR (near IR, at least -- the IR used for the
kind of shots which were shown during the Gulf war, and the later even
in Iraq is a much longer wavelength of IR.
I believe that modern digital SLRs filter the IR out at the
focal plane, just before the light reaches the CCD.
And -- since you posted to the digital-slr newsgroup, it is
reasonable to assume that you are not asking about the filter for a film
Best of luck,
