The Formatt Hitech 77mm HD Combination Hot Mirror/ND 2.4 Filter has been specially formulated as a result of extensive research into applications for molecular A.C.T. dyes. The filters give more of a neutral gray without the specular effects from the particulate coatings of the current neutral density and neutral density graduated filters, which allows the user more precise control.
