นักว่ายน้ำมุมมองจากด้านบนในสระสีเขียวอมฟ้า

An ultra-wide cinematic photograph shot directly top-down above [a single swimmer] floating just beneath the surface of a clear swimming pool. The water is deep teal and turquoise, filled with shimmering sun-caustic patterns across the entire frame. The swimmer is positioned slightly left of center near the upper half, with curly [brown hair] spreading in the water, one arm arcing upward across the right, and the lower body fading into darker depths. The face is obscured by a minimalist matte [beige] rectangle, creating an anonymized editorial aesthetic. Natural midday sunlight, realistic underwater refraction, soft cyan-teal color grading, subtle film grain, and a serene, isolated mood. Vast negative space of rippling pool water on both sides, with no text and no borders.
