I got low to the water with my wide angle lens picking up as much of a reflection as possible in the wet sand and small pools of water where the surf was breaking. The sky was much brighter than the beach, and in order to hold detail I used my Singh Ray 3 stop reverse grad ND for an exposure of 2 seconds at F14. This did a great job of perfectly balancing the light, but I felt I needed a longer exposure time to ghost out the water and record some movement in the sky creating a more surreal image. At 16mm using my Solid ND filter was not an option due to vignetting caused by the thick filter. I used a technique that I has worked for in the past by setting my Nikon to do a multiple exposure of 10 frames at the 2 second base exposure. Shooting each image, one after the other, recorded the water at different places for each frame as well as the clouds in essence giving me a 20 second exposure and the effect I was after.
