IR light is invisible to the human eye, but by using a special filter you can let only the infrared light hit the camera sensor. Not all digital cameras are IR sensitive, but the Fuji S20 Pro and some others are.
The image was made with the camera on a Tripod and a Hoya R72 filter held in front of it. The camera was also set in black and white mode. The filter is so dark that long expsoures are required.
You can read all about how I did it at:

and there is a story on doing it using Photoshop also on-line in that same November 2004 issue of eDigitalPhoto magazine.
