77mm Infrared Filter R72

The Hoya 77mm Infrared Filter can be used to shoot infrared photography on digital cameras or infrared film. The filter blocks all visible light outside the red and infrared range of the spectrum and creates photos that can be processed to get interesting and stunning images that look surreal because objects reflect visible light and infrared light differently. Please note that the use of this filter requires scenes that are very bright to start with.
