This 55mm Mist Diffuser Black No. 0.5 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. 0.5 is similar to filters rated 1/8 when compared to cinematic mist filters.
The cinematic mist effect is created by equally distributing a fine black nano powder between two layers of optical glass then bonding them together. This filter is made of optical glass to retain image detail, but the glass is not multicoated to provide enhanced flares. The slim aluminum frame can be used on wide angle lenses without vignetting.
