A photorealistic low-angle shot from underwater looking up at a young adult European woman in a swimming pool. The woman is standing chest-deep in the water, facing the pool edge with her torso, while her back is turned toward the camera. She is wearing a black wet t-shirt that is clinging tightly to her skin, darkened and saturated by the water. Beneath the water, she wears a black wet glossy lycra thong over dark nylon pantyhose, with the fabric exhibiting a high-sheen wetlook texture, clinging to her skin and legs. Her skin and hair are visibly wet with water sheen. She has her arms resting on the pool edge. The camera is positioned at the bottom of the pool, capturing a low-angle view looking up at her legs and posterior through the clear water. Cinematic lighting, realistic water refraction, caustic light patterns, high detail, 8k resolution, professional photography.
