Infrared film, available in both black-and-white and color formats, is a relatively recent development. Color-infrared (CIR) film, sometimes referred to as "false-color," is the most common form. It was originally developed by the military for detection of camouflage, a concept based on the ability to distinguish between real vegetation and surfaces that have been merely painted green or covered with freshly cut brush or green netting. With color-infrared photography, painted surfaces and dead or dying vegetation were easily discriminated from live, healthy vegetation, and it was not long before the many agricultural applications of CIR technology became apparent to the civilian community.

Infrared aerial photography is a powerful tool. Not only can it be used to document changes to the environment, the health of forests, wetlands, bays and oceans, but it can ... be used to document and monitor such items as damage to roofs, the tracking of dairy farm out flows, pinpointing the source of, and monitoring, insect or disease infested vineyards, or sites contaminated by toxic chemicals, and many more applications.

Infrared imaging with film cameras requires expensive and hard-to-find films and difficult developing procedures. Digital cameras... require nothing but an inexpensive filter and a small investment of time. You can open up a new world of visual opportunities in both color and black and white. To get started, you will need a filter or two and a few tests to determine your digital camera's particular sensitivity to infrared light. Each camera model differs so you'll want to develop your own set of guidelines. The images here were shot with the Nikon D1.

Infrared view of Costa's Hummingbird by flash illumination. This photo was made with conventional (refractive) lenses, an OM T-10 ring flash and two OM T-32 flash units, and a Wratten 87 filter. The image was scanned directly from the negative using a flatbed scanner. Kodak HIE film development was with Kodak HC110 dilution B (8cc:300cc) at 24 degrees Centigrade for five minutes.

Infrared photography has been around for at least 70 years, but until recently has not been easily accessible to those not versed in traditional photographic processes. Since the charge-coupled devices (CCDs) used in digital cameras and camcorders are sensitive to near-infrared light, they can be used to capture infrared photos. With a filter that blocks out all visible light (... frequently called a "cold mirror" filter), most modern digital cameras and camcorders can capture photographs in infrared. In addition, they have LCD screens, which can be used to preview the resulting image in real-time, a tool unavailable in traditional photography without using filters that allow some visible (red) light through.

Infrared photography is sometimes placed on the outside edge of the mainstream photographic world. To the uninitiated observer infrared photography conjures up television images of car thieves speeding away from police helicopters during the dark hours of the night, only to be caught hiding beneath bushes beside a darkened home as their hot bodies light up the camera monitor in the police chopper like Bedouin camel herders atop a Sahara sand dune.
