Black & White Infrared • False Color Infrared
About Infrared Photography
Images of the world captured in infrared are at once eerily strange and yet hauntingly familiar, giving them a surreal feel. It is not for everyone. One is tempted to delve into the science behind IR to unearth the magic behind it, but I’ve found eyes glazing over when I drone on in that vein.
In black and white IR photography blue skies and water appear black or dark grey as they absorb nearly all infrared radiation. A photo captured on a bright day may thus be misunderstood to be a night scene. Plants, flowers, and clouds reflect most IR, thus appear white or light grey
Digital infrared photography requires a specially modified camera. Many IR cameras capture some color artifacts, which can be manipulated either in post-processing or by a camera’s built-in software to render false color schemes.
