Mornington Pier is currently undergoing some major reconstruction, so on my first outing with my new Hoya ND x400 filter I was able to experiment.

This image is as shot (just converted from RAW to JPEG). Shot with a Canon EOS 7D & EFS 17-85mm lens with an ND x400 filter, tripod mounted.

1.6 sec exposure, F 20, ISO 100, 24mm.
