This 82mm Black Mist 1/4 and 1/8 Filter Kit from NiSi can be used to create a cinematic look by lowering contrast and highlights within the frame to balance the tonal range between highlights and shadows. Black mist diffusion filters are also commonly used to help soften wrinkles, blemishes and create a flattering image of a subject. Black mist suppresses highlights and lifts shadows for well-balanced contrast. Light sources maintain a strong center with a pleasing glow from the light source. Beyond portraiture, black mist filters can also be used in other applications, such as night photography, landscape, and still life, to create a cinematic atmosphere by adding extra blooming and gradients to the highlights in a scene. Any direct light source will become more film-like, with a smoother, buttery texture around the highlights.
Made of optical glass, the filters in this kit have strength grades of 1/4 and 1/8, the filter effect becomes approximately twice as strong as a grade number increases. Each filter features a 82mm aluminum ring, and the kit includes a convenient storage case.
