The Hitech 165 x 200mm 0.6ND Hard Graduated Filter is a hard-edged neutral density filter. The 0.6 density helps to 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. Neutral density filters do not affect the coloration of the image.

This filter measures 6.5 x 8" / 165 x 200mm and is compatible with the Hitech 165mm filter holder. It is constructed out of CR-39 dyed resin. The 0.6 density provides 2 stops of reduction in light from entering the lens.
