Ritratto in biblioteca illuminato dal sole

A highly realistic candid indoor photo of a young East Asian woman studying alone in a quiet sunlit library or reading room, seated at a wooden desk and framed from mid-torso up behind several out-of-focus wooden chair backs in the foreground. She has dark brown to black hair tied in a low ponytail with a center part, and wears a simple light gray knit sweater. An open book lies in front of her and a white insulated tumbler stands on the desk to her right. Strong warm morning or afternoon sunlight streams in from a tall window on the right side, illuminating the right edge of her hair, shoulder, desk, and the book pages, while the rest of the room remains softly dim. The composition is telephoto and observational, with shallow depth of field, creamy foreground blur, natural shadows, and a quiet contemplative mood. In the background, include a white standing air conditioner against a dark wood wall partition and muted interior details of a study room. Vertical portrait orientation, documentary realism, subtle film-like texture, natural skin and fabric detail, no stylization, no text, no extra people, no posed smile, just a focused studying moment.
