Infrared photography has been around for at least 70 years. For many years working with infrared film had been quite difficult, because it required: loading the camera in total darkness, extensive exposure bracketing, special developing, special ability in evaluating the photographic results before the pictures were printed etc. However, the last couple of years photography by infrared light has become much easier. CCD and CMCS chips used in digital cameras and camcorders are sensitive to near-infrared light, so with a digital camera, infrared filter that blocks out the visible light, and a tripod anyone can get infrared photos. The main advantage of digital cameras is that the have LCD screens, which can be used to preview the resulting image in real -time. Therefore, infrared photography has become a useful tool with many applications in archaeology and in the conservation of works of art.
