蓝色金属罐体阀门与黄铜管俯视特写

写实工业产品摄影风格，俯视近景特写，一个蓝色喷漆金属圆顶表面占据画面主体，表面有划痕、污渍和边缘掉漆，中央凸起银色六角螺母接头，左侧连接一根呈暗黄铜色的圆柱形短管，管口中空发黑且表面粗糙，右侧为黑色棱纹旋钮，下方有一个带内六角孔的小型圆形金属螺塞，纯白背景，对象居中并几乎充满画面，顶光在蓝色漆面上形成明亮高光，金属部件下方有柔和阴影，细节清晰，近方形画幅，机械工业质感。

Realistic industrial product photography, overhead close-up, a blue painted metal domed surface dominates the frame with scratches, grime, and chipped edges, a raised silver hex nut fitting at the center, an aged brass-colored cylindrical short pipe extending to the left with a dark hollow opening and rough surface, a black ribbed knob on the right, a small round metal plug with a hex socket below, plain white background, centered composition filling most of the frame, top lighting creating bright highlights on the blue paint and soft shadows under metal parts, crisp mechanical details, near-square aspect ratio, industrial texture.
