Definition: Colour infrared film (CIR)

Category: Land Use/Land Cover

Colour infrared film is often called "false-colour" film. In contrast to black and white or colour films, the
film emulsion is sensitive for infrared radiation. Healthy green vegetation is a very strong reflector of
infrared radiation and appears bright red on colour infrared photographs. Objects that are normally red
appear green, green objects (except vegetation) appear blue. The primary use of colour infrared
photography is vegetation studies and forestry. http://ec.europa.eu/eurostat/ramon/statmanuals/files/KS-34-00-407-__-I-EN.pdf#page=39
