Contents
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.
Note:
- Normal ISO speed values do not apply to this film.
- A filter is necessary for most applications.
- This film may not be suitable for a high degree of enlargement.

Handle this film only in total darkness. Test your camera, film holders, processing equipment, and darkroom to ensure that they are opaque to infrared radiation. Load and unload your camera in total darkness. Store loaded film holders and cameras in subdued light, or total darkness if possible. Do not use a safelight during handling or processing.
Infrared films are susceptible to static markings at low relative humidity. If static problems persist, grounding the camera may be necessary to avoid a buildup of static electricity.
High temperatures or high humidity may produce unwanted quality changes. Store unexposed film at 55¡F (13¡C) or lower in the original package. Always store film (exposed or unexposed) in a cool, dry place. For best results, process film as soon as possible after exposure.
Protect processed film from strong light, and store it in a cool, dry place. For more information on storing negatives, see KODAK Publication No. E-30, Storage and Care of Photographic Materials--Before and After Processing.
We cannot give exact speed numbers for this film because the ratio of infrared to visible energy varies, and most exposure meters measure only visible radiation. Make test exposures to determine the proper exposure for your application. For trial exposures under average conditions, use the meter settings in the table on page 3. Use these settings with exposure meters marked for ISO, ASA, or DIN speeds or exposure indexes; they are based on development in KODAK Developer D-76.
To enhance the infrared effect on the film, you must use a filter over the lens (or light source) to absorb the ultraviolet radiation and blue light to which the film is also sensitive. A KODAK WRATTEN Gelatin Filter No. 25 (red) works well for most daylight applications. This filter blocks UV radiation and blue light; however, it passes red light that allows visual focusing. If you want to record only infrared radiation, use a filter that blocks all UV and visible radiation, such as KODAK WRATTEN Gelatin Filter No. 87, 87C, or 89B. Your choice of filter depends on the photographic effect you want to create.

You cannot make exact meter readings to determine exposure for infrared films. Exposure meters are not calibrated for infrared radiation, and the ratio of infrared to visible radiation varies with the light source.
Make trial or bracketing exposures over a five-stop range to determine the proper exposure for your application. Under average conditions, use the following speed ratings to make starting-point exposures with handheld meters or through-the-lens light meters. For through-the-lens camera meters, make your readings before mounting the filter over the lens. Then ignore the meter reading/readout after attaching the filter.

Lenses do not focus infrared radiation in the same plane as visible radiation. Because infrared radiation is longer in wavelength than visible radiation, the focus point is further from the camera lens. Therefore, the lens must be moved slightly farther from the film to focus an infrared image. This focus difference is most critical when using filters to block all visible radiation from the film.
Most camera lenses have an auxiliary infrared focusing mark. Consult your camera manual for the appropriate use.
For best definition, make all exposures at the smallest lens opening that conditions permit. If you must use large apertures and the lens has no auxiliary infrared focusing mark, establish a focus setting by trial and error. Try extending the lens by 0.25 percent of its focal length beyond the correct focus for visible light.
For example, a 200 mm lens would require a 0.50 mm extension as 200 mm x 0.0025 = 0.50 mm.

Use the appropriate guide number in the following table as a starting point for your equipment. Select the unit output closest to the number given by your flash manufacturer. Then find the guide number for feet or metres. To determine the lens opening, divide the guide number by the flash-to-subject distance. If the negatives are consistently too dense (overexposed), use a higher guide number; if they are too thin (underexposed), use a lower number.

Do not use a safelight. Handle unprocessed film in total darkness.
Darkrooms must block all infrared radiation as well as light. Painted windows, plastic sheeting, etc., though opaque, may freely transmit infrared radiation and fog this film.
Note: Infrared films are susceptible to static markings at low relative humidity. Handle with care in the darkroom. If static electricity problems persist, grounding the camera may be necessary during loading and unloading to avoid a buildup of static electricity.
Multiply the normal (unfiltered) exposure time by the filter factor.

The various pictorial, scientific, and technical applications of this film may require negatives of different contrast indexes. The following starting-point recommendations are intended to produce a contrast index close to that listed in the table. Make tests to determine the best development time for your application.
Note: Development times shorter than 5 minutes may produce unsatisfactory uniformity.
With small single- or double-reel tanks, drop the loaded film reel into the developer and attach the top to the tank. Firmly tap the tank on the top of the work surface to dislodge any air bubbles. Provide initial agitation of 5 to 7 inversion cycles in 5 seconds; i.e., extend your arm and vigorously twist your wrist 180 degrees.
Then repeat this agitation procedure at 30-second intervals for the rest of the development time.

Agitate continuously for the first 15 to 30 seconds by raising and lowering the basket, rack, or spindle 1/2 inch. Do not agitate the basket, rack, or spindle for the remainder of the first minute. Then agitate once per minute by lifting the basket, rack, or spindle out of the developer, tilting it approximately 30 degrees, draining it for 5 to 10 seconds, and reimmersing it. Alternate the direction of tilting the basket, rack, or spindle.
