6.6 x 6.6" IRND Filter Density:0.9 Due to imaging sensors' greaterThe Tiffen 6. 6 x 6. 6" IRND Filter is a combination of both an infrared control filter and 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
