The Hitech 150 x 170mm 0.3, 0.6, and 0.9 ND Hard Graduated Filter Kit contains a range of 3 hard-edged graduated neutral density filters offering exposure reduction in 1, 2, and 3 stops respectively. A graduated ND filter helps to darken skies and other bright areas of the image by placing the density at the edge of the filter and tapering it towards the center of the filter plane. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
These filters measure 5.9 x 6.7" / 150 x 170mm and are constructed from specially dyed CR-39 resin.
- Kit contains 0.3, 0.6, and 0.9 hard-edged neutral density graduated filters.
