Chest-up portrait in a 3:4 vertical aspect ratio

. Create a Medium chest-up portrait in a 3:4 vertical aspect ratio, shot at eye level with a short telephoto look equivalent to an 85mm full-frame lens. The subject stands approximately 1.2-1.5 meters from the camera, with shallow depth of field creating a smooth, soft background blur and gentle falloft.
Composition is centered, with relaxed shoulders slightly angled, the head gently tilted to camera-left (subject's right), chin slightly lowered, and direct eye contact into the lens.
Lighting consists of a single dominant warm backlight combined with soft frontal fill. A diffused frontal key light is positioned slightly above eye Level, low contrast, warm color temperature around 3800-4200K. Directly behind the subject, a large circular backlight forms a soft-edged glowing halo centered behind the head, with a smooth gradient falloft. The backlight is strong enough to create clear separation and a warm glow around the hair and shoulders. Shadows are soft and minimal, naturally forming under the chin and along the jawline. Overall contrast is moderate-cinematic but realistic.
The background is a smooth matte studio wall featuring a warm orange-to-amber gradient. A large circular glowing halo is perfectly centered behind the head, creating strong subject-background separation through luminous rim glow rather than artificial effects.
Wardrobe includes a casual matte-texture jacket worn over a simple light-colored t-shirt, with relaxed fit and natural drape. Hair is shoulder-length, natural, slightly tousled, with soft organic strands subtly catching the rim light. No visible accessories. Makeup is minimal and natural, non-glamorous.
The visual style must be fully photorealistic with a cinematic studio aesthetic and a warm monochromatic palette dominated by amber tones. Preserve natural skin texture, micro-details, and realistic pores-no smoothing o beautification. Maintain high detail and realistic micro-texture renderi.
Use the uploaded image strictly as the face identity source. Preserve exact facial proportions, bone structure, micro-expressions, natural asymmetrif 382 and authentic skin texture. Do not stylize, beautify, idealize, alter faciall structure, or change age, ethnicity, or expression. All scene elements-Lighting, pose, camera, wardrobe, and background must follow this templa exactly. The uploaded image contributes facial identity only.
No pose alterations, no camera or lens changes, no lighting color shifts, no halo repositioning, no background replacement, and no style drift. No ani24,4 illustration, caricature, plastic skin, HDR look, over-sharpening, beauty filters, face distortion, resemblance drift, or expression exaggeration.
Output must be 4K UHD resolution with minimal film-like grain, natural sharpness focused on the eyes, and a final look that feels editorial, cinematic, and warm.
