Having visited before I knew exactly what image I was after here. The sky was clear, unlike in the mountains that we were about to visit, so I used a combination of the Lee Big Stopper and a polariser to get an exposure of two minutes to smooth out the sea conditions which we pretty smooth in the first place and, as you can see, was see through as well.

Camera - D7000
