Silhouette of a person standing on a beach, facing the ocean during sunset or sunrise. The sky and water have a bright, reflective quality, and the overall appearance is in black and white. Beach scene at sunset with the sun low on the horizon, a person bending down near the water, and scattered clouds in the sky. Waves gently roll onto the shore, with golden light reflecting off the water and wet sand.
