深灰磨损金属锭静物

横向超宽画幅的写实微距静物摄影，一件长方形铸造金属锭横置于暗色中性背景上，深灰近黑的做旧金属表面，边缘圆钝，带划痕、凹坑、氧化斑驳和粗糙磨损质感；金属锭左侧有竖排压印数字500，中部偏右有椭圆形凹陷，内有数字10形压印。顶视俯拍，物体几乎填满横向画面，柔和漫射光，边缘有细微高光，低饱和暗色调，突出金属表面细节，极宽全景比例。

A photorealistic ultra-wide macro still life of a rectangular cast metal ingot resting on a dark neutral background. The ingot has a dark gray-black tarnished surface, rounded edges, scratches, pitting, oxidation patches, and rough worn texture. On the left side are vertically arranged stamped digits 500, and toward the center-right is an oval recessed hallmark containing digits 10. Top-down view, the object fills the horizontal frame, soft diffused lighting with subtle edge highlights, low-saturation dark tones, highly detailed metal surface, very wide panoramic aspect ratio.
