Thinking about an ND filter for waterfall shots. Help me filter out the bad options.

Puns aside, genuine question: I want that silky long-exposure water look for some falls near here. Is a fixed 6-stop the move, or do the variable NDs not deserve their sketchy reputation anymore? I don't want to spend good glass money on something that adds a weird X pattern to my sky.

Cheap variable NDs are where the X pattern lives. A decent fixed 6-stop plus your polarizer covers waterfalls fine. Bring a tripod, even a wobbly one beats no tripod.

Fixed 6-stop, no contest. Variable NDs have gotten better at the high end but at that price you could just own two fixed ones. Also try around 1 to 2 seconds first — full silky is pretty, but a bit of texture in the water often looks more like water.

Two seconds it is. I'd hate for the shot to fall flat. The waterfall, however, should fall as flat as it likes.
