Photorealistic full-body portrait of a young woman standing knee-deep in a calm forest stream, completely nude, no clothing, no fabric, no sheer cloth, nothing covering her body. She has shoulder-length dark brown hair with soft waves falling over her shoulders, fair skin with subtle natural sheen from water, soft feminine face looking slightly downward with a calm, contemplative expression, full lips slightly parted. Her body is slender yet curvaceous with natural breasts, soft belly, and smooth thighs. One hand rests gently near her lower abdomen, the other hangs relaxed at her side. Soft diffused natural daylight filtering through the dense green forest canopy, misty atmospheric haze, wet skin glistening, water gently reflecting around her legs. Background is blurred lush green foliage and trees. Highly detailed skin texture, realistic anatomy, cinematic lighting, sharp focus on the subject, shallow depth of field, 8k, ultra-realistic photography style. No text, no watermarks, no UI elements, no logos, no overlays of any kind.
