黑板粉笔手写字母

正面摄影：一块复古深色石板黑板，表面富含擦除粉笔灰纹理，用软白粉笔手写单词 "WONDER"，混合粗体大写块字与几个装饰性手绘星形和下划线卷曲装饰。每字高约 12 厘米，粉笔笔触自然变化——重压笔迹粗宽、轻提笔迹纤细、在石板纹理上偶有跳白。黑板上有前次书写被不完全擦除的模糊文字残影。35mm 镜头正面拍摄，f/5.6，正面平光减少反光，通过粉笔痕迹呈现完整石板纹理。底部粉笔槽放着几块折断的粉笔。色调：深石板灰绿、温暖白粉笔、淡幽灵灰擦除残影、粉笔槽上的粉尘。

A straight-on photograph of a vintage dark slate chalkboard, the surface rich with the texture of erased chalk dust, showing the word "WONDER" hand-lettered in soft white chalk using a mix of chunky block capitals and a few decorative hand-drawn stars and underline swirls. Each letter is about 12 cm tall, the chalk strokes showing natural variation — thick pressure strokes, thin upstrokes, occasional skip marks where the chalk skipped over the slate grain. The board has the faint ghost of previous writing partially erased. Shot with a 35mm lens, f/5.6, flat frontal light to minimize glare, revealing the full texture of the slate grain through the chalk marks. A chalk tray at the bottom holds broken chalk pieces. Color palette: dark slate grey-green, warm white chalk, faint ghost-grey erased marks, dusty chalk residue on tray.
