The Tiffen 4×5.65″ IR 85 ND Filters (Full Set) combines infrared correction with neutral density filtration for digital cinema cameras with extended infrared sensitivity. The set provides multiple ND densities, allowing cinematographers to control exposure while maintaining preferred apertures and shutter angles in high-light environments. Designed to reduce infrared contamination caused by stronger ND filtration, these filters help preserve accurate color reproduction and consistent image quality across the visible and near-infrared spectrum.
