This was taken at the Lands End beach in San Francisco. When a big wave came in it landed in a flat section behind the rock. Then as the water receded it created this pattern of ripples in the sunlight. A simple thing but I thought it was pretty awesome.
This image is a composite of three images all taken from the same location. The first image was a long exposure of the water receding and forming this pattern. To do that I had to use a small aperture and a neutral density filter. Then, I added the waves on the left from another image that was a short exposure since a long exposure makes the sea appear calm. Finally a third image was taken of a gentleman walking along the beach.
To create this image I stitched all three back together to convey a sense of what I saw on that lovely Sunday afternoon at the beach.
