Cokin Infrared 720 (89B) Filter

The Cokin P007 Infrared 720 (89B) filter blocks virtually all visible light and passes wavelengths from 720 nm upward, creating the dramatic pale foliage and dark skies typical of infrared photography. Equivalent to the Kodak Wratten 89B, it suits the Cokin P (M) system and is optimized for both digital cameras and infrared film.
