珊瑚覆盖的水下古城遗迹

水下古城电影级宽幅镜头，大理石柱廊与断裂拱门被珊瑚礁和海扇覆盖。镜头置于 12 米深处，沿主干道望向远端坍塌圆形穹顶建筑。青绿色光柱从水面穿透而下，形成耶稣光，照亮在石柱间穿梭的银色鱼群。鹿角珊瑚、脑珊瑚与橙色管状珊瑚密布每块石面，一只海龟在中景悠游。石灰岩被苔藓染绿。色调：深蔚蓝、阳光青绿、象牙石灰岩、珊瑚橙、银色鱼光。16mm 广角，边缘略带色差模拟水下光学折射。氛围壮观、忧郁、超凡脱俗。

A breathtaking underwater cinematic wide shot of a submerged ancient city, its marble colonnades and broken archways now colonized by sprawling coral reefs and draped in flowing sea fans. The camera is positioned at 12 meters depth, looking along the main boulevard toward a collapsed domed rotunda at the far end. Shafts of turquoise and aquamarine light pierce the water from the surface above, creating god-rays that illuminate clouds of iridescent silver fish weaving between the columns. Coral growth — branching staghorn in pale white, brain coral in mustard yellow, and soft orange tube coral — encrusts every stone surface. A sea turtle glides lazily at mid-frame. The stone itself is barnacled limestone, tinted green with algae. Color palette: deep cerulean, sunlit turquoise, ivory limestone, coral orange, and silver fish-flash. Lens: 16mm fisheye-adjacent wide, slight chromatic fringing at the edges to suggest underwater optical physics. Mood: awe-inspiring, melancholic, otherworldly.
