Glass Filters: HD ND Filter

Category: Standard N.D

High Definition Specific neutral density filter.

Having undertaken detailed research with DPs 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 colouration 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 colour 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.

NDs are made in different grades according to the level of light reduction. The standard grades are 0.3, 0.6, 0.9 and 1.2 which equate to 1, 2, 3 and 4 stops of light reduction. Heavier densities can be manufactured to order.
