Noir Portrait: Dark Alleyway

"Generate a highly detailed, ultra-realistic portrait of a young adult person standing in a dark alleyway, with the shadows and darkness casting a moody, film noir atmosphere, using a Leica SL2 camera with a 75mm lens, aperture f/1.8, ISO 800, and a shallow depth of field, with the subject looking directly at the camera with a subtle head tilt, and a blurred background of alleyway walls and trash cans."
