The 85 x 85mm Resin Standard Neutral Density Pro Kit from Formatt Hitech contains three solid neutral density filters with a range of options for exposure reduction. The filters included are 0.6, 0.9, and 1.2 densities, offering a reduction of 2, 3, and 4 stops of light, respectively. An ND filter creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. These filters measure 3.35 x 3.35" / 85 x 85mm and are constructed from specially dyed CR-39 resin.
