Formatt Hitech Firecrest Graduated ND Filter Kit (150 x 170mm)

The 150 x 170mm Formatt-Hitech Firecrest Graduated ND Filter Kit contains 3 Firecrest graduated ND filters, ranging in density from 0.6 to 1.2 to provide a selective reduction in exposure from 2 to 4 stops. Graduated neutral density filters help to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in other regions of the image. The ND effect is densest at the edge and taper to clear by the middle, with a soft-edged line of transition between the density and the clear areas. These filters are designed to be used in the vertical orientation as the line of transition runs parallel to the short side of the filter.
