The Formatt 77mm Hot Mirror/Neutral Density (ND) 1.8 HD 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.

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.

Benefits

Formatt's HD Neutral Density solid and graduated filters are available in all the popular round screw-in sizes, all the standard square sizes
All Formatt filters are finished with a unique edge frame offering maximum protection against chipping, surface scratches and enables easy handling and cleaning
With the filter description on top of the frame it also makes identification of the filter much easier especially when filters are stored in cases on location
Formatt HD Neutral Density filters have the same densities and light stops as the Kodak Wratten Standards
Formatt's Neutral Density Filters are a response to the many DPs and cinematographers who find that it is important to shoot as wide open as possible to minimize depth of field, especially with HD

Neutral Density Filters Have Four Main Uses

To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations
To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
