Vue scindée cinématographique d’un requin tropical et d’un ciel au coucher du soleil

Subject: A cinematic shot of the upper and lower waterline of a tropical ocean, crystal-clear turquoise waters and coral reefs below; a dramatic sky with isolated white clouds and the setting sun above. Underwater: A large shark glides toward the camera, intricate texture, colorful corals and small reef fish in the background, soft sunbeams and caustic light patterns, rich green, blue, violet, and cyan colors. Above water: A lone woman sits astride a surfboard, her legs submerged in the water, silhouetted against a brilliant golden-orange sunset, a distant island with palm trees on the horizon. Perfectly sharp waterline running horizontally down the center of the frame, droplets on the lens, subtle distortion at the surface edge, both halves sharp and detailed. Ultra-realistic lighting, natural color gradation, high-detail nature photography. 16K HD
