A young adult European woman swimming underwater in a tropical sea, captured from a high-angle rear view. Her black hair is soaking wet, plastered to her head and face. She is wearing a wet, translucent white ribbed tank top that clings tightly to her skin, revealing her silhouette, paired with a wet, shiny black lycra thong that is slightly askew. She is barefoot, wearing diving fins on her feet, a diving mask on her face, and a scuba tank strapped to her back. The scene is filled with underwater plants and schools of fish. Her breasts shift naturally under the wet tank top with her movement, and streams of air bubbles rise steadily toward the surface. The lighting is natural underwater sunlight, emphasizing the wetness of her skin, the dark soaked fabric of her clothing, and the glossy water sheen on her gear. Photorealistic, high-detail, cinematic underwater photography.
