Sunset ReefThis luminous photograph of Swamis Reef in Encinitas captures ultralow tide at sunset, when the exposed reef becomes a mirror for the sky. Pools of still water shimmer in deep indigo and cobalt, reflecting bands of gold and magenta as the sun dips toward the horizon. Dramatic clouds sweep overhead, creating a sense of vast, peaceful space where ocean, sky, and stone all glow with the last light of day.
