电影中景，粉笔板背景提示
一个为 Nano Banana Pro (v.053) 设计的详细提示，用于生成一个电影般的特写镜头：主体靠在一块写满了字的黑色黑板上，指定了服装、灯光（柔和、漫射、中调）和色彩分级（暖色、去饱和的深褐色，带一点黄绿色调）。

中文提示词
主体图像，电影中景，略带低角度视角。主体靠在某个表面上，呈四分之三侧面，若有所思地凝视着镜头外侧。身穿一件褶皱的白色纽扣衬衫，袖子卷起，一条深色有纹理的领带松散地打着结，下身是棕色斜纹棉布裤。站在一块宽阔、磨损的黑色黑板前，黑板上密密麻麻地写满了白色粉笔字、图表、箭头和哲学文本。灯光柔和、漫射、中等亮度，来自右侧，营造出柔和、开放的阴影，均匀照亮场景，没有刺眼的强光。整体图像明亮，对比度适中，保留了衬衫和皮肤中间调的细节。色彩分级为温暖、去饱和的棕褐色，带有明显的绿黄色调，这是暖荧光灯下老旧胶片的典型特征。黑色略微提亮，但未被压暗。整个画面呈现中等 50mm 胶片颗粒感。
原始提示词
Image from subject, cinematic medium shot with a slight low-angle perspective. The subject is leaning back against a surface, in a three-quarter profile view, gazing thoughtfully off-camera to the side. Wearing a rumpled white button-up shirt with rolled-up sleeves, a dark textured necktie loosely knotted, and brown chino pants. Standing against an expansive, worn black chalkboard covered in dense white chalk writing, diagrams, arrows, and philosophical text. The lighting is soft, diffused, and medium-key, originating from the right, creating gentle, open shadows and evenly illuminating the scene without harsh highlights. The overall image is brightly lit with moderate contrast, preserving detail in the mid-tones of the shirt and skin. Color grading is a warm, desaturated sepia with a distinct greenish-yellow tint, characteristic of aged film under warm fluorescent light. Blacks are slightly lifted but not crushed. Medium 50mm film grain is present throughout.
