The world of infrared light cannot be seen by the unaided human eye. Infrared photography presents an entirely different way of looking at landscapes, architecture and the shapes and forms of the human body.
CCD's in digital cameras are extremely sensitive to infrared light. When the IR blocking filter (aka "hot mirror") has been removed from the light path inside the camera and an infrared passing filter is placed on the front of the lens, digital cameras that normally shoot color become a tool for capturing infrared.
