The Tiffen 4×5.65″ IRND Black Pro-Mist Filters (Full Set) combines infrared neutral density filtration with the Black Pro-Mist diffusion effect to provide simultaneous exposure reduction and image softening. Available in multiple densities and diffusion strengths, these filters reduce digital sharpness, lower contrast, soften skin detail, and create controlled highlight halation while helping maintain accurate infrared color performance on modern cinema cameras.
