The Hoya Pro-1 Digital ND64 filter is a dark neutral density filter which reduces the amount of light entering the lens by 6 stops. This is a great filter for reducing shutter speeds to capture motion such as in water, foliage or people. For example, in bright daylight the slowest shutter speed possible without a filter might be 1/60 sec at f/22. By adding the ND32 filter, a shutter speed of 1 sec would be possible.
Another use of the ND64 would be controlling depth of field. With a strong ND64, a much wider aperture can be used. Wide apertures like f/1.4 and f1.8 create a very shallow depth of field and have the effect of isolating the subject from the background. Creative possibilities are endless with this type of filter.
