This 82mm Mist Diffuser Black No. 1 Filter from Hoya diffuses light sources to create a soft glowing effect around highlights. It reduces overall contrast, but especially in the shadows, and helps to create a cinematic look and film feel in still images and video. The effect is an increase in halation or "blooming" of highlights and specular light sources, plus a reduction in contrast, wrinkles, and skin blemishes for a softer, more romantic look. The effect of the Mist Diffuser Black No. 1 is similar to filters rated 1/4 when compared to cinematic mist filters.
