Aerial Photography are images captured via satellite or by high flying aircraft. As we know, light and energy are emitted from the sun. The types of light emitted are divided into visible and invisible spectrums. The invisible near-infrared wavelengths of light are captured by electronic sensors or film designed to pick-up these wavelengths. From the early 20th century to present day black and white aerial photography has been used. It was much more widely used up until the second world war however. When color infrared film hit the market, less aerial photographs were taken using black and white infrared film.
