Hoya 55mm PRO1D ND16 Neutral Density Filter

The ND16 is a dark neutral density filter with a filter factor of 16, meaning there is 4 stop light loss. This is a great filters for slowing down shutter speeds to capture motion. An example: In daylight, maybe the slowest shutter speed possible without a filter could be 1/60 sec at F/22 By adding the HOYA PRO1 ND16, a shutter speed of 1/4 sec would be possible.

Another use of the ND16 would be controlling depth of field. With a strong ND16, 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.
