Wordy Wednesday #164 “Shooting Infrared Film”

Infrared radiation has some of the same properties as visible light. It can be focused and reflected like visible light and can be aligned and polarized. Infrared film is sensitive to IR radiation, some ultraviolet radiation, and to all wavelengths of visible light but not as sensitive to green light. Eastman Kodak prviously offered a black and white infrared film called High Speed Infrared and Ilford still sells SFX 200 film that has sensitivity to 720nm, which can be extended to 740nm by using a deep red filter. (More about nanometers here.)

IR film must be loaded into your camera in complete darkness and you will also have to unload it in total darkness and, most likely, process it yourself. Historically infrared films had the reputation that they cannot be processed in plastic tanks but JOBO tanks have been tested to be compatible with IR films. Caveat: Double check this before investing. Since many film changing bags are not opaque to IR radiation, your biggest problem will loading the film onto the reels when processing which is best done in a proper darkroom to assure against fogging.

The above image was originally captured on a snowy day in the 200-year old village of Dickeyville, Maryland using Kodak’s black and white infrared negative film. The film frame was scanned as a positive image and converted into what you see here.. No exposure data recorded.
