The LCD screens on these cameras further simplify the process because you can preview the images in real- time. This feature was unavailable in traditional photography without using filters that admit at least some visible (red) light. Before we begin, find out whether your camera has an infrared block- ing or “hot mirror” filter installed. If so, you may have to disassemble the camera to remove it (of course, this could void your warranty). To find out if your camera has such a blocking filter, see if it picks up the beams emitted by a common infrared remote control. These fairly bright beams are easy to see in the LCD preview area of the camera. If your camera does not have an LCD, try capturing an image of the beams while depressing any button on the remote. If there is no visible infrared beam in the image, you’ll know there is an infrared blocking filter installed. Olympus, Agfa, and Nikon digital cameras do not have the filter, so you can use them out of the box.
