红色20L旧金属油桶

写实3D产品渲染或棚拍静物风格，一只红色旧金属杰里罐汽油桶，正面略偏左视角，顶部金属提手与左上角密封盖，桶身上部压印“20L”字样，表面布满锈斑、褪色、划痕和黑色污渍，桶身有X形冲压加强筋和中部矩形凹印，孤立置于纯白背景，柔和均匀棚光，高细节，金属磨损质感清晰，3:4竖幅构图。

Photorealistic 3D product render or studio still life, a weathered red metal jerrycan, slight front-left view, metal top handle and upper-left sealing cap, embossed “20L” near the top, surface covered with rust patches, fading paint, scratches and dark grime, X-shaped pressed reinforcement ribs and a central rectangular recess on the body, isolated on a pure white background, soft even studio lighting, high detail, clear worn metal texture, 3:4 vertical composition.
