Tiffen IRND 0.6 (4x5.65")

The Tiffen 4 x 5.65" Full Spectrum IRND 0.6 Filter is a combination of both an infrared control filter and a 0.6 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.
