Noir Detective Alley

Photograph a noir detective leaning against a brick wall in a rain-soaked alley circa 1948. Illuminate the scene with a single tungsten streetlamp creating dramatic chiaroscuro and long shadows. Add glistening cobblestones, swirling cigarette smoke, and blurred headlights in the distance. Render in high-contrast monochrome with cinematic grain, shallow depth of field, and subtle lens flare.
