I love shooting at Cannon Beach in Oregon… and this was my first experiment in long exposure photography. I used a 30-second shutter speed to capture the shot.
I had to wait until long after the sun went down to get this shot. At the time, I had only a single 4-stop Neutral Density filter, so I waited until the light was low enough for me to push the shutter speed to 30 seconds. An added benefit of waiting was that I was able to get the deep blue colors of twilight.
