37mm Neutral Density Filter  ND2 ND4 ND8 Optical Glass Filter

Neutral Density filter evenly reduce the amount of light passing through the lens without effecting color. Ideal for reducing bright light in large aperture situations when a narrow depth is field is needed. Neutral Density Filters are often used to achieve motion blur effects with slow shutter speeds

Four main uses:
1) Enables slow shutter speeds to be used, especially with high-speed films, allowing film to record movement in subjects such as waterfalls, clouds, or cars.
2) Decrease depth of field by allowing wider apertures to be used, in turn helping to separate subjects from their background.
3) Decrease the effective ISO of high-speed film and allow it to be used outdoors in bright situations.
4) To allow picture and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes that can cause overexposure.
