NiSi Allure Black Mist Diffusion Cinema filters reduce the contrast that can lead to excessive sharpness with modern cinema, DSLR and mirrorless camera lenses.
Diffusion filters are considered essential in many productions to create specific effects or simply to soften light or reduce the appearance of blemishes in the actor’s skin, particularly useful in close-up work where modern technology can produce an image that is too sharp and not flattering.
Black mist filters are created with the addition of small black flecks so will still create a halation around points of light and soften skin, however, controls the light differently and leaves shadows unaffected.
Both White and Black mist come in strengths ranging from 1/8 to 1 stop – with 1 stop being the strongest effect. If you have not used mist filters before, a good starting point is 1/4.
