The B+W 100 x 150mm 701 Graduated 0.3 ND Filter is a graduated neutral density filter that helps to specifically darken skies and other bright areas of the image. The filter is densest at the edge and tapers to clear by the middle of the filter. Neutral density filters do not affect the coloration of the image and the 0.3 density provides a 1 stop reduction in light from entering the lens.
The Multi-Resistant Coating (MRC) is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters.
