Hoya 58mm PRO1 Digital Neutral Density ND32x (5-stop) Filter

Note: Above picture is just for reference.

The 58mm Pro 1 Digital Neutral Density 32x Filter from Hoya is an ultra thin filter that permits you to shoot and create images that would not ordinarily be possible to capture. This filter effectively reduces your ISO by 1/32 (5 stops). This means a shot normally taken at 1/500 @ f/11 can be shot at 1/15th second at the same aperture. Designed with the outdoor shooter in mind, this filter helps reduce the amount of light entering the lens. This translates into the use of wider apertures and, thereby, permits the photographer to have more control over his depth of field. This is especially useful when shooting outdoor portraits when you wish to establish more of a separation between subject and background. The result will be a sharp, clear subject with a soft background. The ultimate value of this filter is its ability to allow you to use high speed ISOs under bright light conditions

　

This effect can be used to create even more exciting images such as the "whooshing" effect of a mountain stream or the chaos of city traffic where one car appears to blend into the other. The operative effect is to enhance movement within the shot.

　

Neutral Density Filters Have Four Main Uses

• To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars

• To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background

• To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation

• 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
