A photorealistic shot of a young adult European woman swimming underwater in a tropical sea, seen from a high angle behind her. She has wet black hair plastered to her head and face. She is wearing a soaking-wet white ribbed tank top that is transparent and clings tightly to her skin, revealing the natural movement of her breasts as she swims. She wears a wet, glossy, black lycra thong that is slightly shifted, and she is barefoot with scuba fins on her feet. She is equipped with a diving mask on her face and a scuba tank on her back. The environment is filled with underwater plants and tropical fish, with air bubbles rising regularly toward the water surface. The scene captures natural, fluid underwater swimming movements, with highly realistic wet skin, water sheen, and light refraction through the water, cinematic lighting, 8k resolution, highly detailed.
