复古金属钟形装置白底静物

写实产品静物摄影，1:1方形构图，正面平视，居中对称，一件复古做旧金属钟形装置占据画面主体。主体为灰银色与暗黄铜色调的金属材质，表面有磨损、划痕、污渍和氧化痕迹。顶部中央竖立一根拉杆，拉杆顶端为圆形旋钮，底部通过带铆钉的装饰性金属支架固定在顶盖上；左侧可见一个圆形侧窗或端口结构；底部基座正面横向排列三个圆形旋钮或螺栓，边缘有厚重金属圈。纯白无缝背景，柔和棚拍灯光从上方和侧面照亮，金属高光清晰，阴影干净，工业复古质感，无人物。

Realistic studio product photography, square 1:1 composition, straight-on front view, centered and symmetrical, a vintage aged metal bell-shaped apparatus occupying the main subject. The body is gray-silver and dark brass-toned metal with visible wear, scratches, stains, and oxidation. At the top center stands a vertical lever with a round knob, fixed by a decorative metal bracket with rivets on the lid; on the left side a circular porthole or port structure is visible; along the front of the base are three round knobs or bolts in a row, bordered by a heavy metal rim. Plain white seamless background, soft studio lighting from above and the side, clear metallic highlights, clean shadows, industrial vintage texture, no people.
