After taking the photo posted here I made my way back down off the rock. Once I got down on the sand, I noticed the fact that the sky was reflecting in the thin layer of water left by the retreating waves. So, I walked out to where it was about ankle deep when the waves came in and set my tripod up low to maximize the reflections. The water was causing the tripod to sink into the sand. As a result, I didn’t take my usual 7 exposures. Instead I only took 3 because if I had to mess around with the settings the tripod would have shifted between photos.
