IMAX 航拍冰川史诗（Style 锚定法）

Style: Epic, IMAX-scale aerial cinematography, 70mm large-format texture, ultra-clear deep blacks, restrained color grade favoring glacial blues and pale gold sunlight. A vast tidewater glacier meets a still arctic fjord at dawn. Cracked ice fields stretch toward distant snow-capped peaks. A faint mist rises off open water; a lone iceberg drifts mid-frame. No people, no boats. Cinematography: - Camera: aerial wide shot, slight downward angle, slow forward push toward the glacier face - Lens: 24mm spherical; deep focus from foreground floes to distant peaks - Lighting: low-angle sunrise key from camera right; cool ambient fill from open sky - Mood: monumental, hushed, geological Actions: - Camera glides forward at steady altitude; an ice shelf calves silently in the distance - The chunk slips into the sea, sending a slow, wide ripple toward camera - The iceberg rolls a quarter turn, revealing translucent blue underbelly Background Sound: Distant low ice groan; wind across open water; one sharp crack at calving. No music.
