I may be wrong, but my guess is that the IR filter

in the camera is optimized for the particulars of

the sensor characteristics, so no stock front filter

would exactly compensate for its loss - though

white-balancing may compensate if things are not

too odd, once the IR is mostly blocked. If you

are removing the filter to permit observation by

IR illumination (I hope for good purpose! ;-),

you will need to provide that illumination (and

it can be invisible). BTW, IR does not "look

through clothes", contrary to popular opinion...;-)

Trusting that your motives are good (and since

web-cams are cheap), good luck with this, and

let us know the results (and, BTW, an IR filter

can be rather expensive...).
