场景与主体：
一幅4:3画幅的超写实摄影，以纪录片风格呈现一幅绘于标准绿色教室黑板上的大型粉笔画。画面采用居中构图的中景，完整聚焦黑板壁画。前景为一张教师讲台，为壁画提供了真实的空间尺度与场景代入感。
视觉细节：
壁画主角是《海贼王》中的罗罗诺亚·索隆。他以标志性的战斗姿态占据画面中心，口中紧咬一把白色粉笔绘制的和道一文字，双手各持一把刀（拟用粉笔表现），呈现经典的三刀流架势。绘画细节丰富：绿色的短发与黑色的头巾用粉笔浓淡表现体积；神情坚毅专注，左眼的伤疤清晰可见；标志性的腹卷和长裤用不同力道的排线塑造阴影与褶皱。画作右侧或下方可用清晰的白色粉笔书写其名号“海贼猎人索隆”。整个画面保留了粉笔特有的粉尘哑光质感，可见用于塑造肌肉线条和衣物纹理的交叉排线笔触，以及色彩自然晕染的痕迹。
环境与光线：
场景设定在一个标准的日本学校教室。柔和、非直射的环境光来自头顶荧光灯与左侧窗户的日光混合，色温中性，均匀照亮画面，既避免黑板反光又凸显了粉笔纹理。教室氛围安静、空无一人，充满学术感。
摄影规格：
使用35mm全画幅传感器与35mm定焦镜头拍摄。光圈f/5.6，中等景深确保壁画清晰锐利，前景讲台元素轻微虚化。快门速度1/60秒，ISO 400。相机位于站立时的视平线高度，距离足以完整框取画作与讲台。
英文提示词（Prompt）：
Scene & Subject:
A photorealistic, documentary-style photograph in a 4:3 aspect ratio, capturing a large-scale chalk drawing on a standard green classroom blackboard. The composition is a centered medium shot focused entirely on the mural. A teacher’s desk in the immediate foreground provides authentic scale and contextual grounding.
Visual Details:
The mural depicts Roronoa Zoro from “One Piece” in his iconic three-sword style stance. He dominates the center, biting the hilt of Wado Ichimonji (rendered in white chalk) and holding two other swords aloft. The artwork is intricate: his green short hair and black bandana are shaded with chalk; his expression is determined, with the scar over his left eye clearly visible; his haramaki and trousers are detailed with hatching to create folds and shadows. White chalk text such as “Pirate Hunter Zoro” may be written beside the figure. The image preserves the dusty, matte quality of chalk, with visible cross-hatching strokes defining musculature and fabric texture, and natural color smudges.
Environment & Lighting:
The setting is a standard Japanese school classroom. Soft, diffuse ambient light from overhead fluorescent fixtures mixed with daylight from left-side windows provides even, neutral-white illumination. This lighting prevents glare on the board while highlighting the chalk’s texture. The atmosphere is quiet, academic, and suggestively unoccupied.
Photographic Specs:
Shot with a 35mm full-frame sensor and a 35mm prime lens at f/5.6 aperture, achieving a moderate depth of field that keeps the mural in sharp focus while slightly softening the foreground desk. Shutter speed 1/60s, ISO 400. The camera is positioned at a standing eye-level height, set back to frame the entire artwork and the desk.
