B+W 702 77mm 25 Percent MRC Graduated Neutral Density Filter

he B+W 77mm Graduated 25% Grey 0.6 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 abruptly fades to clear by the middle of the filter. The design of this filter incorporates a rotating mount to allow precise positioning of the grad line along the horizon line. Neutral density filters do not affect the coloration of the image and the 0.6 density provides a 2 stop reduction in light from entering the lens.
