I absolutely love having the ocean as a subject for long exposures. No matter how wild and aggressive the seas are, a 30 second or minute long exposure will calm the scene right down and leave the viewer with a whole different world to look at.
On the day I shot this, the wind was absolutely howling across the water and the ocean was ripping into the gash in the lava rock on the left of the frame. Despite what may seem like a furious scene from my description, I found myself completely at peace just watching the water come in and go out. What better way to capture the mood than with a long exposure.
