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 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 5.65 / 101.6 x 143.5mm. 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.
Neutral density filter provides a 6 stop exposure reduction. Water White optical glass for excellent clarity.4 x 5.65 / 101.6 x 143.5 mm. 0.3 (1 stop) 0.6 (2 stop) 0.9 (3 stop) 1.2 (4 stop) 1.5 (5 stop) 1.8 (6 stop) 2.1 (7 stop).
