The B+W 77mm MRC 702M Soft-Edge Graduated Neutral Density 0.6 Filter helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. The design of this filter incorporates a rotating mount to allow for precise positioning of the gradation along the horizon line. Neutral density filters do not affect the coloration of the image and the density provides up to a 2-stop reduction in light from entering the lens.
To prevent internal ghosting and reflections while maximizing light transmission, each glass surface includes eight layers of anti-reflection coating. This Multi-Resistant Coating (MRC) also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters.
This B+W filter is constructed from optical glass for clarity and color fidelity. An F-Pro brass filter ring is provided for durability as well as jamming prevention.
