一片银叶，把白光折成一条彩虹

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.

实验静物摄影，一片薄银金属叶悬在透明三棱镜后方，白光穿过棱镜在灰白纸面上落下一条窄彩虹，银叶边缘局部反射彩色。留白横构图，焦点清晰，没有烟雾或额外发光特效。
