The HOYA R72 infrared filter is specifically designed for infrared photography with digital cameras and infrared film.

Infrared light begins in the bright red area of the visible spectrum at 750nm and increases above 1000nm. This light is not visible to the naked eye. Looking through the R72 filter appears almost opaque because only light from the very high red end of the visible spectrum and infrared light passes through the filter.

Infrared photography produces very interesting, sometimes stunning and creative results in a photograph, as objects reflect infrared light differently than normal light.

Due to the nature of infrared light, the filter factor and exposure compensation vary significantly from visible light and largely depend on lighting conditions.

The filter fully transmits light at 760nm – 860nm (infrared spectrum) with a light transmission of 95%. The HOYA R72 is made from high-quality Hoya glass housed in a precision frame made of rigid aluminum. Consistent quality, made in Japan.

It can be combined with colored black and white contrast filters such as R25 (red), K2 (yellow), O (orange), or other colored filters to alter color performance or contrast.
