[Dimension filter] ND filter can reduce the amount of light and prevent overexposure when taking pictures during the day. Since it is variable, you can adjust the light intensity from ND2 to ND400. This is very convenient because you don't have to have a large number of filters. It can create thread-like water currents and light flows, and can be used in various scenes such as streams, the ocean, and waterfalls.

Keep rotating the filter and the shadows will disappear naturally. This phenomenon is not a quality issue, but a natural physical phenomenon caused by the rotation of the variable ND.
