photorealistic cinematic low-key portrait of a young man

Create a photorealistic cinematic low-key portrait of a young man with light stubble, shown from the chest up in a tall vertical 4:5 frame, positioned slightly left of center. His chest is not facing the camera. His torso is turned away at a three-quarter angle, and his head is bowed deeply forward, looking down toward the ground, with his face in profile turned toward the right of the frame. He wears a loose black crew-neck t-shirt that is almost invisible in the darkness. His messy, wavy, dark hair falls forward over his forehead. Lighting (very important): There is only ONE single thin ray of cool-white light, coming diagonally from the right edge of the frame. The ray is narrow and tightly controlled. It does not spread, does not fill the room, and does not illuminate the background. The ray touches only the outer edges of his hair, where individual curls and strands glow with delicate rim light, plus a tiny sliver of his nose, lips and jawline and a faint touch on the side of his neck. Nothing else is lit. Darkness: The man is almost entirely in complete darkness. His face is NOT clearly visible: about 80% of it is lost in deep black shadow, and only the thin edge of the profile can be made out. His eyes, forehead, cheek and the back of his head are completely hidden. His torso, shoulders and shirt dissolve into pure black. The background is pure black with no visible walls, no gradient and no ambient light, leaving vast empty negative space above and around him. Mood and style: Crushed blacks, minimal highlights, dramatic chiaroscuro, a faint haze visible only inside the single ray, realistic skin texture, fine hair detail, 85mm lens, shallow depth of field, moody and melancholic. No fill light, no soft ambient glow, no second light source. No illustration, no anime, no CGI, Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
