Is a combination of both an infrared control filter and a 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.
