Formatt's High Definition Neutral Density glass filters (also known as NDs) produce a Grey neutral tone and are used to reduce light, enabling more control over exposure and depth of field without affecting color or contrast. ND Glass filters are especially useful in bright light conditions to avoid overexposure. When using wider lenses they adjust exposure correctly, allowing for reduced depth of field. This enables highlighting of the principal subject and taking the foreground or background out of focus. This filter is also blended and has soft graduation, enabling the ability consolidate two filters and many effects into one.

Having undertaken detailed research with DOPs and other users of High Definition (“HD”) equipment, it became apparent that HD cameras require a more optically pure Grey neutral density filter to avoid some of the coloration issues which are inherent in their use, particularly at low light levels. Formatt’s new HD NDs (available in standard and graduated versions) provide this with no color shift of the type which can be found in some standard ND filters. Formatt recommends the purchase of HD ND filters as they are the most optically pure ND filters available and, although designed for HD can be used with any type of camera. They are the same price as the standard ND range.
