8-second cinematic POV underwater video, ultra-realistic.
0-3s: Camera submerged, looking forward through clear blue water with natural sunlight filtering from above; drifting particles and subtle refractions. From behind the viewer, a school of salmon surges forward, swimming rapidly in the same direction as my view, passing just beside and ahead of me. Their scales catch sunlight, bubbles trail, motion blur and water turbulence realistic.
3-8s: After the fish pass, camera starts rising smoothly toward the water surface. Light intensifies, more particles floating, water distortion and refractions shift naturally. By 8 seconds, view is just under sea level, looking up at the wavering surface underside with ripples visible.
Style: cinematic, documentary-style realism, fluid camera motion, natural lighting, high physics fidelity (water movement, fish movement, light reflections).
