Description
The Tiffen 4×5.65″ IRND Filter Kit includes four densities — 0.3, 0.6, 0.9 and 1.2 — reducing visible light by 1-4 stops respectively while also cutting far-red and infrared pollution.
HD sensors have greater low-light sensitivity and correspondingly higher IR susceptibility — standard ND filters make infrared contamination more visible as density increases. These filters combine an ND with a matched IR control filter, eliminating infrared spill while keeping the extra exposure control a neutral density filter provides.
