A photorealistic, high-detail shot of a young adult European woman with tanned skin and wet, slicked-back brown hair, lying on her back in the shallow, crystalline water at a sandy beach. She is topless, with her bare breasts exposed, wearing only a tiny black thong. The fabric of the thong is soaking-wet, clinging tightly to her skin, appearing as a deep, saturated obsidian black with a high-gloss, wet sheen. She is actively performing mouth-to-mouth resuscitation on a man lying on his back in the shallow surf, his skin also glistening with water. The scene captures the realistic texture of wet, sun-kissed skin, water droplets clinging to their bodies, and the interaction of the shallow tide swirling around them. Natural, bright daylight, sharp focus on the subjects, cinematic composition, 8k resolution, hyper-realistic skin textures, water refraction, and sparkling highlights on the wet surfaces.
