Ultra-Realistic B&W Athletic Man Portrait Prompt

Ultra-realistic black and white portrait photograph of a handsome athletic young man in his early 20s, with wavy voluminous light brown tousled hair, strong jawline, intense direct gaze at camera, wearing a tight-fitting black short-sleeve t-shirt showing defined muscular arms and shoulders, a thin chain necklace barely visible. He is standing with his back to the camera, turned three-quarter view looking back over his left shoulder, arms crossed confidently over his chest, right shoulder leaning against a rustic textured brick wall. Urban alleyway location with old weathered brick walls on both sides, dark shadowy background creating depth and dramatic atmosphere. Natural side lighting from the left creating high contrast, Rembrandt-style soft illumination on the face, deep shadows in the background, highlighting muscle definition on arms and shoulders. Shot with 85mm portrait lens, medium shot from waist up, shallow depth of field with slightly blurred background, subject positioned on the right third of the frame following rule of thirds, eye-level camera angle. Cinematic editorial fashion photography style, masculine moody aesthetic, GQ magazine quality, dramatic chiaroscuro lighting, professional studio-grade black and white conversion, sharp focus on subject, film grain texture, 8K resolution, photorealistic.
