The Black Mist Filter 1/8 from NiSi is a classic style diffusion filter for lenses with a( 67mm,72mm,77mm,82mm) filter thread. Inspired by the popular cinema range "Allure Mist Black" and recreated as a circular filter. Compatible with both still imaging or video, a Black Mist filter lowers contrast by suppressing and diffusing highlights and lifting shadows to help balance the tonal range of the image. It creates a cinematic look and is also commonly used to soften wrinkles, blemishes and creates a flattering image of a subject. The effect is most effective when capturing light that diffuses softly when backlit, creating a transparent light that looks like it was taken with a high-quality vintage lens. This filter is constructed from optical glass and is available in diffusion grades of 1/8, 1/4, and 1/2; the diffusion effect becomes approximately twice as strong with each grade number increase. Each optical glass surface features NiSi's Nano coating for an improved beading effect when in contact with water, oil, or grease for greater cleaning efficiency. Constructed with a high-quality brass frame for enhanced durability and jamming prevention.
