SUBJECT: [Subject] POSITION: Centrally aligned, standing vertically exactly on the natural boundary between shimmering sea water and a fine-grain golden sand beach. QUALITY & STYLE: A highly detailed, hyper-realistic, top-down product photograph (flat-lay style) with stunning 8K resolution and clarity. The overall aesthetic is natural, fresh, and luxurious. ENVIRONMENT & BACKGROUND: The scene is clean and precisely divided. The left half is composed of crystal-clear, sunlit turquoise water with a distinct, complex light-refraction (caustic) pattern dancing on the water bed and surface. The right half is fine, golden beach sand, with a gentle, frothy wave cresting precisely around the base of the central [Subject], leaving a trail of sea foam on the sand. The sand is adorned with scattered natural seashells of varying sizes and shapes. LIGHTING & COMPOSITION: Strong, direct, natural high-angle sunlight (like midday sun) casts a clear, sharp shadow of the central [Subject] onto the sand. The composition is a direct, symmetric overhead view, split between water and sand with the [Subject] as the focal point. ASPECT RATIO 3:4.
