GPT Image 2.5 Sunburst プロンプト - 暖色室内光の無造作スマホ自撮り

Subject: A young woman with fair skin and dark blonde/light brown hair loosely tied into a low or mid-height bun, with a few wisps framing her cheeks. Expression and mood: Her head is slightly tilted, with a subtle, playful smile. She looks directly at the camera with a soft gaze, conveying a friendly, relaxed, casual social media snapshot vibe. Makeup: Very natural, minimal makeup—defined lashes, lightly flushed cheeks, and lips with a natural rosy sheen. Clothing: A white spaghetti-strap tank top with a low scoop neckline. The elastic waistband of gray sweatpants or lounge pants is visible. Accessories: A short pearl necklace layered with a finer metal chain. Pose and composition: A close-up, waist-up selfie, with her body turned slightly to one side and her upper body leaning forward a little. Her shoulders create a diagonal line across the frame. She fills most of the image, with the background slightly blurred. Setting: An indoor space with light-colored walls. A simple shelf on the left wall holds small decorative objects, framed photos, or plants, with a black chair nearby. Warm indoor lighting, soft shadows, and an authentic smartphone photo look.
