Film Code Base Letter Code CAT No. 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. 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. 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.
