Function Introduction of ND Lens：
The main purpose of ND filter is to prevent overexposure, for example, it is impossible to select a slower shutter speed when the ray of light is bright outdoors in daytime. However, ND filter will reduce intrusion of light ray even at a slower shutter speed. As a matter of fact, ND filter is applicable when it needs to take the crowd passing by, or take waterfall and water current with longer time of exposure under normal light ray for a blur effect. We are expert in production of ND filters at levels of ND2, ND4, ND8, ND16 and ND32.
