IR photographs with digital cameras

Most digital cameras are sensitive to the near Infrared spectrum, and some cameras like the Sony DSC-F707 will take pictures in complete darkness by using an Infrared Light Emitting Diode. You can use your cameras ability to see in the Infrared Spectrum and take some nifty photos with the edition of an Infrared filter. The filter you need is R72 by Hoya or equivalent filter by another company. The Infrared filter is almost completely opaque, but to the digital camera it looks almost clear.
Another feature your camera should have is the ability to take Black and White photos. If you try and take pictures in the color mode the photos will come out looking magenta or some other shade of red which you will have to manipulate in a photo editing program to change it to black and white.
One of the reasons for choosing the Sony DSC-F707 digital camera was the ability to use screw on filters. Most digital cameras require an adapter to use filters because the camera was designed for the "point-and-shoot" market. The Minolta's high end digital camera will also accept filters, as will all of the digital cameras with interchangable lenses.
