一片銀葉，把白光折成一條彩虹

Experimental still-life photograph: a thin silver metal leaf suspended behind a clear triangular prism. White light passes through the prism and casts a narrow rainbow on gray-white paper, lightly reflected at the leaf edge. Wide negative space, crisp focus, no haze or extra glow effects.

實驗靜物攝影，一片薄銀金屬葉懸在透明三稜鏡後方，白光穿過稜鏡在灰白紙面上落下一條窄彩虹，銀葉邊緣區域性反射彩色。留白橫構圖，焦點清晰，沒有煙霧或額外發光特效。
