I recently tried out my B+W ND110 filter on some coasty water. I liked the results. These were shot using a Sigma 10-20mm on a D80 body using a tripod. Exposure time was around 30seconds each. I shot in Manual because the camera kept underexposing by a long way … I had this idea that the body would adapt to the 10stop reduction in light and adjust shutter speed accordingly but it didn't seem to. Anyways, I liked the results.
