The Benro Master 100 x 100mm ND 3.0 Filter is a neutral density filter with a 1000x filter factor, which provides a 10-stop exposure reduction. Its 3.0 density creates a darkening of the whole image, which allows you to photograph with a wider aperture or slower shutter speed than what is usually required. When you increase your aperture or slow your exposure time, you can control your depth of field and capture movement more easily. Neutral density filters have zero effect on the coloration of the image and are great for pairing with other filters. To prevent reflections and internal ghosting, each glass surface includes multiple layers of anti-reflection coating. These coatings also provide greater protection to the filter and help it to stay clean. The Nano coating used with the neutral density filters provides an additional 13th layer over each side of this filter, producing an improved beading effect when in contact with water, allowing for easy cleaning. This filter is constructed from SCHOTT B270 glass for optical clarity as well as color fidelity, and is 2mm thick.
