This is a Promaster Neutral Density (ND) Filter. This is BRAND NEW in original packaging. These Promaster ND filters have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear gray and reduce the amount of light reaching the film, they have no effect on color balance. The main uses of this filter are: - To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background. - To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas, etc. WE SHIP IN 1 BUSINESS DAY and we package professionally.
