黑色电影侦探半身

Vertical half-body cinematic noir portrait of a hard-boiled detective inside a dark 1940s office at night. Single venetian blind shadow pattern cast across the face and the dark trenchcoat, low-key key light from the left, deep shadows on the right. Fedora tilted slightly forward, lit cigarette held casually with a thin smoke curl rising. Composed mid expression, eyes catching the light. Vertical 9:16 composition, head and chest framing. No text on the wall, no badge visible, no watermark. Classic film noir cinematography quality, photorealistic skin and fabric textures, subtle 35mm grain.
