Kodak HIE, Hi-Speed Infrared Black & White Negative Film, ISO Does Not Apply, 35mm Size, 36 Exposure, USA

KODAK PROFESSIONAL High Speed Infrared Film is a high-speed film with moderately high contrast, sensitive to light and radiant energy to 900 nanometres (nm) in wavelength. It is useful for haze penetration and for special effects in commercial, architectural, fine art, and landscape photography. With development variations, you can use this film for scientific, medical, aerial photography, and document copying. You can also use it for photomicrography, photomechanical, and remote-sensing applications.

Infrared films are sensitive to infrared radiation, some ultraviolet radiation, and to all wavelengths of visible radiation (light). They are, however, not as sensitive to green light.

Whatever the ultimate purpose of your photographs, infrared photography provides unusual effects obtainable by few other means.
