Black and white aerial photos are a type of remote sensing map type, which involves the detection and measurement of radiation of different wavelengths reflected or emitted from distant objects or surfaces. Aerial photographs can be divided based on the film type, and photographic film can be coated with different light-sensitive emulsions, each sensitive to specific wavelengths of electromagnetic radiation. Black and white aerial photos are a type of remote sensing aerial photo in which the black and while emulsion proves sensitive to the same wavelengths as the human eye. The above picture is an aerial photo/map type of remote sensing clearly using black and white light-sensitive emulsions, sensitive to the same wavelengths as the range that human vision allows and is why we can observe the wavelengths recorded on the film.
