Preserve the subject's exact facial identity, facial proportions, hairstyle, beard pattern, skin texture, age, ethnicity, and natural features. The person in the final image must remain instantly recognizable as the uploaded individual. Do not beautify, alter, or redesign the face. Create an ultra-realistic fine-art black-and-white low-key studio portrait in a 4:5 aspect ratio. Composition: Medium close-up framing, filling approximately 65-70% of the frame, showing only the head, neck, shoulders, upper chest, and upper arms. Wardrobe: The subject wears a plain black fitted crew-neck T-shirt with no logos, graphics, or text. Pose: The body is rotated approximately 45° away from the camera in a strong three-quarter pose, with the left shoulder (image left) closest to the camera. The chest faces toward the left side of the frame rather than directly toward the viewer. The head is turned only slightly farther left than the torso, maintaining a natural three-quarter angle instead of a full profile. The eyes look off-frame toward the upper left, focused on something slightly above eye level. The gaze should feel subtle, thoughtful, and contemplative—not looking into the camera, not looking directly left, and not looking high into the sky. The chin is slightly lowered, creating a calm, serious, introspective expression. Lighting: Use a single soft key light positioned from the upper left. Illuminate only the camera-facing side of the forehead, eye, cheekbone, nose bridge, lips, beard, and neck. The opposite side of the face should gradually fade into deep black shadow, with the far cheek, ear, jawline, shoulder, and most of the torso completely disappearing into darkness. The black T-shirt should blend seamlessly into the shadows so that the lower chest, arms, and body are almost invisible, leaving the illuminated side of the face as the primary focal point. Background: Pure matte black with absolutely no texture, patterns, objects, or distractions. Style: High-contrast monochrome, cinematic fine-art portrait with soft shadow transitions, realistic skin texture, natural hair detail, subtle film grain, and an intensely dark, minimalist atmosphere. Ultra-detailed, museum-quality studio photography, 8K realism.
