红色做旧液化气钢瓶静物

照片级写实3D道具渲染，一只老旧红色金属液化气钢瓶置于纯白背景中央，正面平视全身构图，竖幅3:5。钢瓶为圆润罐体，顶部有红色护栏与中央铜色阀门，阀体带旋柄和六角结构；瓶身正面有残存的白色喷漆字样Gas和WARNING，表面布满划痕、掉漆、污渍与氧化痕迹；中部有横向凸起接缝，底部有金属底座圈并带两个圆孔。棚拍柔光，正面均匀照明，轻微高光表现金属磨损质感，主体清晰，白底无杂物。

Photorealistic 3D prop render of an old red metal liquefied gas cylinder centered on a pure white background, straight-on full frontal view, vertical 3:5 aspect ratio. The cylinder has a rounded tank body, a red top guard frame, and a central brass valve with a handwheel and hexagonal fittings; faded white stenciled lettering Gas and WARNING remains on the front; the surface is heavily scratched, chipped, stained, and oxidized; a horizontal raised seam runs around the middle, and the bottom metal ring has two circular holes. Soft studio lighting, even frontal illumination, subtle highlights showing worn metal texture, sharp subject, clean white background.
