The HOYA Sq100 Black Mist is an effect filter that diffuses the light and reduces the overall contrast at the same time. This creates a classic cinematic look that makes the filter perfect for both photography and videography. The Sq100 Black Mist is available in two densities - 1/4 and 1/8 - so that the artist can freely choose the desired strength for each individual situation. The Sq100 Black Mist creates a smooth, soft effect by diffusing light around light sources while reducing overall contrast. This reduces the overall sharpness and gives the image a classic and timeless look with a touch of vintage, similar to the style commonly found in cinema. The filter is also great for landscape photography as it can diffuse sunlight, making it ideal for shots where the sun is setting or the sun's rays are falling through the crowns of trees.
