For the technically inclined...shot with a 8x neutral density filter. This is my first time using it, or owning one...other shots may follow. (Underwater Aquatic life at La Jolla was bad, worse than I have ever seen it. I tried two different sites a half a mile apart. {the walking was good for me...with the swimming, fitbit says I did 168minutes of cardio, which is...radically unusual for lazy me}...but except for fat sea lions sitting (? yes honestly sitting under very occluded water with me), there was almost nada alive in this marine reserve and underwater park. But sometimes bad water makes for good outcomes, it forced me to try this new technique.
