Designed with professional landscape photographers in mind, this 170 x 190mm Benro 170x190mm Soft Edge Graduated ND Filter 3-Stopfrom Benro 170x190mm Soft Edge Graduated ND Filter 3-Stophas an 8x filter factor that provides a 3-stop exposure reduction in selected areas. This specific model features a soft edge in its center, fading gradually from completely clear to darkened as we move towards the top. This allows the filter to keep bright skies under control without creating a line in the image, making it ideal for pictures without a clearly defined horizon line.

The Master Series filters are made with Schott B270 glass and finished with several different layers of coating. These layers increase the resistance of the glass to avoid scratches and help keep the surface waterproof, making it easier to clean when shooting in inclement weather. Additionally, the filter is designed for a neutral performance that avoids affecting color rendition and curtails the unnatural colors found in some pictures with high contrast.
