The Formatt Hitech 43mm HD Combination Hot Mirror/ND 0.6 Filter has been specially formulated resulting from extensive research into the applications of molecular A.C.T. dyes (Absorption Cell Technology). This unique filter gives more of a neutral gray look without the specular effects that you see in current neutral density and graduated neutral density filters - thereby allowing you more precise control.
Determining which neutral density filter yields ideal results for any given lighting situation takes knowledge, experience and a collection of such filters. Speaking generally, the 2-stop value (ND 0.6) effectively compensates average situations.
Formatt Hot Mirror Filters - Some digital still cameras can have increased sensitivity to infrared light that may cause color rendition problems. The Formatt Standard Hot Mirror Filter is designed to remedy this problem by reflecting most infrared light.
HD technology has been targeted towards today's cinema and videographer who are using the latest ultra-sharp cameras and lenses.
Formatt, a company with three generations of professional filter-making experience produces every filter to the highest technical standards. The finest materials, together with state of-the-art production technology have resulted in a standard of optical excellence unmatched anywhere else.
