The Series 9 HD ND 2.4 Filter from Formatt Hitech has been developed to meet the needs of today's modern ultra-sharp HD (High Definition) cameras and lenses. This is an optically pure ND filter - more than a standard Formatt ND filter. It enables the shooter to adjust exposure without affecting potential color shift problems that may occur in low light.
A neutral density filter appears gray and reduces the amount of light reaching the digital sensor or film plane. Neutral Density filters are also used to create some unusual special effects such as capturing the "blur" of the rippling water of a waterfall or the swirling effect of city traffic. Determining which grade of neutral density filter yields ideal results for any given lighting situation takes knowledge, experience and a collection of such filters.
