高分辨率摄影：眼神与自然优雅

ultra realistic portrait photo of a young woman in her early 20s with light brown skin and natural facial features, dark brown hair styled in a slightly messy bun with loose strands framing her face, large expressive brown eyes with natural depth and reflections, full lips with realistic red lipstick texture (not flat color, slightly glossy, natural imperfections)

she is wearing a black sports bra with the word “[BRAND]” printed clearly on the chest in clean, sharp typography, slightly curved following the fabric tension, and a white elastic waistband underwear with “[BRAND]” repeated around the band, high detail fabric texture, elastic tension visible, subtle stitching and micro-folds

her pose is confident and relaxed, shoulders slightly angled, head tilted slightly forward, looking directly into the camera with a soft playful expression, natural posture (not exaggerated)

lighting is soft studio lighting, diffused key light from front-left, gentle shadow falloff on the right side of face, subtle rim light separating her from background, realistic skin highlights (no plastic look)

background is clean white studio backdrop, minimalistic, smooth gradient with slight shadow under subject for grounding

shot with 85mm lens, shallow depth of field, ultra high resolution, detailed skin texture (pores, subtle imperfections), realistic color grading, no illustration or painting style, strictly photographic realism
