Photorealistic Fog in a Quiet Bomb Shelter Interior

Photorealistic interior of a bomb shelter shrouded in dense fog. Cold concrete walls with peeling paint, rusted metal shelves lined with canned goods, a dusty old radio, and a flickering fluorescent light casting a chilly blue-green glow. Dust motes swirl in the damp air as a beam of light cuts through the fog. A heavy steel door stands ajar; shadows pool in the corners. Outside the small porthole window, fog obscures a ruined skyline. Ultra-realistic textures: wet concrete, chipped paint, condensation on glass, rusty metal, and subtle reflections on the damp floor. Cinematic lighting, shallow depth of field, and a tense, quiet mood.
