Features:
 - Neutral density filters like the HAKUBA SUPND4-28 are used to slow shutter speeds with fast films, to decrease depth of field, and to lower the effective ISO of high speed film
 - Neutral density filters are often overlooked by beginning photographers, despite multiple uses
 - The ND filter can be used to lengthen exposure time, creating effects such as white foaming water in landscape photos that seems almost in motion
 - The 4X filter factor used with the SUPND4-28 means, quite simply, that four times as much light is needed for exposure when the filter is mounted
 - For use with lenses featuring 28MM filter threads
