Infrared film and infrared digital sensors are sensitive to a certain portion of the spectrum of light, and by careful filtration, processing and selection of films, infrared aerials can provide invaluable information. IR film is commonly used to produce color-infrared photos. IR imagery uses false color, since we can’t really see the wavelengths recorded on infrared film. The varying reflections produce a contrasting effect (e.g., vegetation vs. water).
