I'm not a 100% sure but I think you could use a polarizer if you don't have a ND filter to cut down the light. Correct me if I'm wrong guys.![]()

Whether you need an ND filter or not depends on lots of things, the lighting, the speed of the water, the smallest aperture you want to use, if you have a tripod or support for the camera, the effect you are after and so on.
If you want to read a bit more have a look at Ron Bigelow's site http://ronbigelow.com/articles/waterfalls-1/waterfalls-1.htm.
There are many other good articles there as well![]()
