A professional studio portrait of an adult woman sitting on the floor, photographed in a clean, high-key studio setup. She is seated in a relaxed pose with one leg folded under her and the other bent in front, gently holding her knee with both hands. She is smiling warmly at the camera, conveying a friendly, confident, approachable mood. She has fair skin, long straight dark brown hair parted slightly to one side, light natural makeup, and small subtle earrings. She is wearing a sleeveless fitted dark gray dress and sheer black tights. Her feet are covered by the tights, no shoes. The background is a soft, seamless light lavender/very pale gray gradient studio backdrop. Lighting is soft and diffused, coming mainly from the front and slightly above, producing smooth skin tones, soft shadows, and a clean commercial look. The composition is vertical, full body visible, centered slightly to the right with negative space on the left. Shot on a high-resolution professional camera, 85mm lens look, shallow depth of field, sharp focus, realistic skin texture, editorial photography quality, ultra-detailed, natural colors, studio photography, 4k, photorealistic.
