ND8 (Neutral Density) Multicoated Glass Filter (58mm) For Fujifilm FinePix S9400W (Includes Filter Adapter)

Neutral Density Filters Have Four Main Uses: 1.To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars. 2. To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background. 3. To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation. 4. To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
