Color Infrared – 08

The technique refered to as color IR is the result of visible light passing through a IR filter, usually Hoya R72, Heliopan RG715 and RG665 filters are used for this technique. The post processing method involves the swapping of the color channels through the Channel mixer tool in Adobe Photoshop.This filters blocks about 95% of the visible light under 720 nanometer. This is why it’s not a “real” IR filter but “near IR” filter and lets you get colorful IR images.
