GPT Image 2.5 Sunburst プロンプト - 冷たい昼光の列車で丸まる乗客

Photorealistic candid train travel photograph, vertical 3:4. An adult woman aged 25+ is curled up on a dark navy seat with geometric woven upholstery beside a large window. Her back rests lightly against a backrest with a beige fabric headrest cover. Both knees are drawn together toward her chest, and both feet, wearing plain white crew socks, rest on the seat cushion. She wears an ivory spaghetti-strap top and light shorts, mostly obscured naturally by her bent legs and arms. Her hands loosely overlap above her knees while holding a clear beverage bottle with a light green cap and pale pink label. A black hair tie circles one wrist, and a rectangular smartwatch is on the other. Long dark brown-black hair falls along her cheeks and shoulders, with a few natural flyaways. Light everyday makeup, pale pink blush, and muted rose-pink lips. Her head is turned toward the window on the left, lips slightly parted, expression quiet and distracted, as though she has just tucked her feet onto the seat and is still watching the passing scenery. Photograph from slightly left of her front, near seated eye level with a gentle downward angle, approximately a 28–35mm equivalent lens feel. Position her on the right, leaving a large area of window on the left, and include her head, bent legs, and sock-covered feet. Outside are pale blue sky, distant water, and a horizontal perforated metal barrier. Light gray carriage panels and a casually cropped armrest complete the setting. Soft cool-white daylight enters from the left, illuminating her cheek, arms, and knees while leaving gentle shadows toward the seat. Preserve natural skin texture, subtle digital grain, moderately clear background details, and the imperfect framing of an ordinary smartphone travel snapshot.
