just to show, my bog standard digital cam with a lcd display shows infra red, dont even have to take the photo (did the remote test) very interesting indeed.

One last thing, this graph shows reflectivity as a function of wavelength for a few common materials:

The biggest changes are that in the IR foliage is really bright and water is really dark.

jps: The only other thing I noticed is that people's eyes look like big black pits, like the nighttime scenes in the Blair witch project. It's really creepy!

Chris: You definitely need to be outside, I couldn't get a single image from indoors. Additionally some more expensive cameras do have IR filters in their lenses so it's worth checking if you can see the light from the remote control before testing anything else.

I couldn’t get it to work. What kind of lighting conditions did you use? I tried it indoors.
Maybe my camera filters out infrared…

that is so cool! can you try it at night, illuminating things with your remote? is there anything else you can only see in ir rather than visible?
