For this shot I used neutral density filters to get an exposure of 10 seconds at f/29.
Another image of waves breaking against the Kona shore just before sunset. This one feels more serene than Kona Coast, Sunset, I but the two photos were taken within minutes of each other along the same stretch of the coast. The key difference being the length of the exposure. For this photo I used a 2.5 second exposure while the other was only 0.3 seconds.
