The Tiffen 6.6 x 6.6" hard edge graduated ND 0.9 filter is a graduated neutral density filter that helps specifically darken skies and other bright areas of the image. The filter is denser at the edge and fades to clear in the middle, with a sharp transition line between the dense and clear areas. Neutral density filters do not affect image colouration and the 0.9 density provides a 3-stop reduction of light entering the lens.

This filter is manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 sheets of optical glass and polishing it flat to a tolerance of 1/10,000th of an inch. This filter measures 6.6 x 6.6" / 167.6 x 167.6mm.
