 Neutral density filter

In photography and optics ,a  neuteal density filter is a filter that reduces or modifies the intensity of all wavelength,or colors of light equally,giving no changes in hue of color rendition.It can be a colorless or grey filter.The purpose os a standard photographic neutral density filter is to reduce the amout of light entering the lens.Doing so allows the photographer to select combinations of aperture,exposure time and sensor sensitivity tat would otherwise produce overexposed pictures.This is done to achieve effects such as a shallower depth of field or motion blur of a subject in a wider range of situations and atmospheric conditions.
