Tiffen Coarse Water White Glass Full Spectrum IRND Filter (105mm, 7-Stop)

This 1-stop, 105mm Tiffen Coarse Water White Glass Full Spectrum IRND Filter is a combination of both an infrared control filter and a 2.1 neutral density filter. An IRND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to infrared 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 a neutral density filter with a comparable infrared control filter to eliminate the spill of infrared light reaching the sensor while still maintaining the extra exposure benefits of a neutral density filter.
