Precision Design 77mm Variable NDX Neutral Density Filter
Enjoy total control of virtually any lighting environment.
With this Precision Design Variable Neutral Density Filter, you can enjoy total control of virtually any lighting environment and reduce brightness without affecting color or depth of field. Simply turn this filter's exterior ring to access any of six ND settings without wasting time changing or adding filters.
Variable neutral density filters reduce intensity of all wavelengths or colors of light equally, resulting in no changes in hue or color rendition. The purpose of standard photographic neutral density filters is to allow the photographer greater flexibility to change the aperture, exposure time and/or blur of subject in different situations and atmospheric conditions. Instead of reducing the aperture to limit light, the photographer can add a ND filter to limit light, and can then set the shutter speed accordingly.
