The Drowned Church Bell — Underwater Ruin

Dive-cam supernatural horror, 8 seconds, 16:9, murky realism. A drowned church in a reservoir, filmed on a diver's camera through green murk: the camera drifts down the nave past rows of silt-covered pews, an altar draped in algae, a crucifix, all filmed through drifting particulate.
0-2s: The slow drift continues up the bell tower's stairs, fins stirring the gloom, the light dimming, until the bell hangs in frame, verdigris-green and enormous in its iron frame. 2-5s: The bell begins to swing though the water is dead still, slowly at first, then with growing force, and the camera's audio picks up a deep bronze toll, muffled and wrong; below in the nave the pews are no longer empty, dark shapes sit in rows facing the altar, swaying with the bell's rhythm, wearing Sunday clothes forty years drowned. 5-8s: The diver's light sweeps the congregation and one shape turns its head toward the beam, its face pale in the torchlight; the bell tolls faster and the frame fills with green murk as the diver recoils.
Subject: the diver's gloved hand and torch occasionally in frame, the verdigris bell, the drowned congregation. Camera: authentic dive-cam drift, unsteady, the torch beam the only controlled light. Lighting: green reservoir murk, the diver's torch beam cutting the dark. Atmosphere: sacred drowned dread. Style: dive-cam realism, silt particulate, muffled audio, desaturated green grade, 24fps.
