Establishing reference photograph of a place: Empty hospital corridor near closed ICU double doors, almost entirely swallowed by darkness, final residual glow fading. Faint cold blue-grey sheen on polished linoleum floor, barely visible door edges, a dim muted gold emergency light dying above the frame. Deep, near-total black dominating the image, no people, no text. Low angle, extreme close perspective, vertical 9:16. Cinematic realism, supernatural thriller, oppressive silence, grief, shallow depth of field, heavy shadows, cold blue-grey and black palette with subtle muted gold accents.
No people, no visible text, no watermark.
