青銅方孔錢的修復臺微距研究圖

Museum-conservation macro still life of a single ancient bronze cash coin with a square center hole, held above a black velvet restoration tray on a delicate archival support; green and umber patina, a tiny conservation brush and unlabeled calipers nearby, cobalt-blue background fading into darkness. Precise cool studio highlights. No text, logos, watermark, or distorted objects.

博物館修復風格的微距靜物：一枚中央有方孔的古代青銅錢幣用纖細檔案支架懸在黑色天鵝絨修復盤上，帶綠色和赭色包漿，旁邊有細小修復刷和無標識遊標卡尺，鈷藍背景漸入暗處。精確的冷調影棚高光。不要文字、標誌、水印或變形物體。
