With the advent of digital cameras it is now possible to photograph infrared light with your digital camera and greatly simplify the infrared photography process. The latest digital cameras are sensitive to infrared light, so much so that manufacturers place a hot mirror filter in front of the sensor to block infrared light to prevent infrared IR light from spoiling regular photographs. It is still possible to shoot digital infrared photography with an unmodified digital camera but the exposures become quite long and in most cases require a tripod, not to mention the need to place an infrared filter in front of the lens to block visible light. All this sure doesn't help the creative infrared photography process. With our digital infrared photography conversion it is now possible to photograph infrared images hand held at low ISO speeds and without the need for infrared filters. Since you no longer need to use an infrared filter in front of the lens it is much easier to change lenses, compose and focus.
Maybe I won't sell that old D20 after all......
