The NiSi 95mm Circular White Mist 1/4 diffuses and softens strong light entering the lens and produces a diffused glowing effect. While the resulting image appears softer and ethereal with little loss of clarity or detail. This filter works by diffusing the light entering the lens with small particles; by spreading the light more evenly, a soft glow is created rather than the sharp, well-defined image when shooting without a filter. The Soft effect of this filter makes it widely used in portrait photography, which can cover up blemishes on the face or skin. For Landscape Photography, using the Soft filter can add glowing mist effects to strong light.
