Film that is sensitive to wavelengths in the near-infrared region.

infrared film

Film carrying an emulsion especially sensitive to “near infrared.” The film is used for tasks such as camouflage detection to distinguish between living vegetation and dead vegetation or artificial green pigment. The film also is used to photograph objects through haze because of the penetrating power of infrared light. Infrared film can also distinguish between aircraft that has no fuel in it and that which is fueled, as the latter will be cooler than the former and this will show up in the film. See also near infrared.

Of course, if transparent shrimp absorb UV light as a means of protection, they could become visible to predators that have UV-sensitive vision." She added, "We haven't tried observing these shrimp with infrared film because no animals are known to detect those wavelengths."
To achieve the maximum effect, it isn't enough just to load your camera with infrared film (and remember always to load and unload this film in complete darkness)--a special filter also needs to be fitted to the lens of the camera.This is because all infrared films are sensitive to daylight as well as infrared, so if no filter is used, the effect of infrared will be largely obscured by the visible light image rendered on the film.

The military involvement in aerial photography led to innovative applications such as the use of infrared film to spot enemy positions through heavy natural cover and the development of ever-longer lenses and finer-grained films to record greater amounts of detail from higher vantage points.
I like using infrared film, because it records heat rather than light, so anything that has heat in it--like a tree, or grass or a person--comes out very white and ghost-like.
