The Formatt-Hitech 150 x 150mm Firecrest ND 0.3, 0.9, 2.4, 3.0 Filter Kit contains 4 Firecrest ND filters, including 0.3, 0.9, 2.4, 3.0 densities to provide 2, 3, 6, and 10 stop reductions in exposure, respectively. By darkening the entire image, you can photograph with a wider aperture or slower shutter speed than normally required for greater control over focus, movement, and brightness.
