What is infrared photography? Infrared photography is of interest to the amateur and commercial photographer and to scientists and technologists because it produces images that are not possible with conventional photographic films. In its practice there is not much difference between infrared and normal photography. The same cameras and light sources can usually be used, together with the same processing solutions. Infrared photography, however, is usually only attempted by skilled photographers, scientists, and technicians with a particular purpose in mind.
Infrared photography films - are sensitive to both the light we can see and some of the longer length (above 700 nm) infra-red radiation. The film is also sensitive in the UV region (below 400 nm).
Infrared photography filter - blocks most of the visible light spectrum and only lets infrared (IR) light pass through
