日系负片风格天台人像

创作一张 {argument name="style" default="日系负片风格"} 的夏季天台人像，光线采用柔和的自然日光，高光略微过曝，低对比度，色彩柔和褪色，并带有细腻的胶片颗粒感。主体 {argument name="posture" default="站立或坐着"} 在天台边缘，姿态放松，微风吹动头发和衣物。主体看向镜头，眼神平静而疏离，不过分摆拍。保持天空开阔，留白充足，背景元素极简，构图呈现不完美的抓拍感，营造出安静、孤独的氛围。画面应具有怀旧、深思、写实和记忆般的质感。使用 2:3 的长宽比。

Create a {argument name="style" default="Japanese negative film style"} rooftop summer portrait with soft natural sunlight, slightly overexposed highlights, low contrast, muted faded colors, and subtle film grain. The subject is {argument name="posture" default="standing or sitting"} near the edge of a rooftop, relaxed in posture, with a light breeze moving their hair and clothing. They look toward the camera with a calm, distant gaze, not overly posed. Keep the sky open with plenty of empty space, very few background elements, an imperfect candid composition, and a quiet isolated mood. The image should feel nostalgic, reflective, realistic, and memory-like. Use a 2:3 aspect ratio.
