Formatt Hitech Firecrest ND Filter Kit (100 x 100mm)

The 100 x 100 Formatt-Hitech Firecrest ND Filter Kit contains 3 Firecrest ND filters, ranging in density from 1.2 to 1.8 to provide a reduction in exposure from 4 to 6 stops. 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.
