Haida NanoPro ND Filter (77mm, 16.5-Stop)

This 77mm NanoPro ND Filter from Haida provides a 16.5-stop increase in neutral density, offering control of available shutter speeds or aperture settings for both still and video applications. Using a longer shutter speed makes it possible to increase image blur to convey a sense of movement, useful when shooting moving water. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background and reducing depth of field.
