Underwater Coral Descent

Serene underwater descent along a vibrant coral wall in clear tropical ocean, mid-morning sunlight piercing the surface in shimmering shafts. A free diver in a matte wetsuit glides downward with minimal fin movement, bubbles streaming in a thin silver trail, past sea turtles, a slow manta ray, and schools of luminescent fish that part around them. Camera descends alongside, initially looking up at the rippling bright surface, then rotating to reveal the coral wall dropping into deep blue void below. Volumetric god rays, floating particulate matter (marine snow), realistic buoyancy and hair movement, caustic light dancing on coral and skin, accurate animal movement and species look, color shifting from turquoise shallows to deep navy. Wide 16mm underwater dome look, organic lens wobble. Sound: muffled aquatic ambience, whale-like distant song, bubbles, heartbeat slow. 2.39:1, 24fps, photorealistic, no fantasy creatures, correct diving posture. ================================================================================
