This 5 x 5" Tiffen Full Spectrum IRND Filter 5x5 7-Stopis a combination of both an infrared control filter and a 7-stop neutral density filter. An IRND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination. When using a standard neutral density filter to counter the increased light sensitivity afforded by the HD sensor, the effects of infrared pollution become more apparent. This filter combines an ND filter with a comparable IR control filter to eliminate the spill of infrared light reaching the sensor while still maintaining the extra exposure benefits of a neutral density filter.

This filter is constructed from Water White glass and is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 5 x 5" / 127 x 127mm.

2.1 Optical Density    ColorCore Water White Glass    Enables Use of ND without IR Pollution    Maintains Color Fidelity    Ideal for HD Cameras

Infrared control filter helps to block infrared pollution from affecting the color fidelity of imagery; this enables a wider color gamut and truer colors, especially noticeable in the darker regions of the image.

2.1 neutral density filter provides a 7-stop exposure reduction.
