纯白背景上的黑色揉皱塑料袋

写实静物摄影，一个黑色高密度塑料垃圾袋被揉皱成不规则团状，袋身布满密集褶皱和皱缩纹理，黑色塑料表面呈现湿润般的高光反射，局部隐约透出微弱彩色杂质痕迹；袋口收拢，边缘向外翻折，整体置于纯白色背景，主体居中并占据大部分画面，近景俯拍特写，摄影棚均匀柔光，突出塑料材质光泽与褶皱立体感，真实日常物件质感，约5:4横画幅。

Realistic still-life photography of a black high-density plastic garbage bag crumpled into an irregular mass, covered in dense wrinkles and creases, with glossy highlights on the black plastic surface and faint traces of subtle colored residue showing through in a few spots; the bag opening is gathered and edges fold outward, placed against a pure white background, centered and filling most of the frame, close-up top-down shot, soft even studio lighting, emphasizing the plastic material sheen and three-dimensional folds, realistic everyday object texture, approximately 5:4 horizontal aspect ratio.
