ND-------Extend exposure time. Try an ND, or neutral density, filter. ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion.
? Neutral density can be adjusted from 3 to 7 stops(ND8/ND16/ND32/ND64/ND128), easy to create different neutral density by rotating the ring. ? The front diameter is larger than the back diameter of this filter, which is specially designed to avoid vignetting at a wide-angle lens. ? Allows the use of slow shutter speeds, with high-speed films or digital cameras, to record movement/image blur in subjects. ? Decrease the depth of field by using wider apertures, which helps separate subjects from their background.
Description
