However, most webcams come with a filter installed to block out IR light. This makes the image less washed out but it keeps you from being able to see in the dark (using IR illumination).” – Link.

I would like to add to this:
I saw this hack elsewhere a few months back.
You can add a small piece of developed film negative where the IR filter used to be, and it will keep the image from washing out so much. It acts like sunglasses for your webcam, but it really just blocks out more visible-wavelength light and lets the IR through.
I haven’t tried using mine as a night-vision via IR type webcam yet, so I don’t know how it affects the image.
I used some kind of spare logitech quickcam I had sitting around, and I never had to cut the lense assembly to do this.
It’s old, but it’s a great concept and very maker oriented. There’s a lot of postings showing up here that are years old, and that’s a good thing. Being an old idea doesn’t mean it’s not of interest to makers. As long as it hasn’t been posted on this blog before, it should be posted.
Besides, it beats another LED throwie posting ;)
There’s an “X-Ray” effect with certain dark colored thin bathing suits, filters and light levels BTW
