**PROMPT — PROFESSIONAL AUTHOR PORTRAIT**
Use the uploaded reference image as the **ONLY identity reference** for the person.
**IDENTITY PRESERVATION — HIGHEST PRIORITY:**
Reproduce the exact same person from the reference image. Preserve 100% of the recognizable facial identity, including facial structure, eyes, eyebrows, nose, lips, jawline, ears, skin tone, natural skin texture, hairline, hairstyle, hair color, facial hair, and all visible tattoos. Preserve the original age and natural appearance. Do not beautify, reshape, smooth, reinterpret, or replace any facial features. Keep the original makeup unchanged if present.
**SCENE & COMPOSITION:**
Create an ultra-photorealistic, premium editorial author portrait of the same person, suitable for a professional German nonfiction author.
The subject is looking directly into the camera with a calm, confident, intelligent, and approachable expression. Relaxed shoulders, natural posture, subtle confidence, and a composed presence that communicates credibility, depth, and intellectual curiosity.
**WARDROBE:**
Elegant black blazer over a plain black crew-neck shirt. Minimalist, timeless, sophisticated styling without visible logos or distracting accessories.
**BACKGROUND:**
Dark charcoal studio background with a subtle gradient and understated depth. Clean, uncluttered, premium editorial atmosphere.
**LIGHTING & CAMERA:**
Professional portrait photography, soft directional key light, gentle fill light, subtle rim lighting separating the subject from the background. Natural skin texture, realistic pores, sharp eyes, accurate skin tones, detailed hair, soft cinematic shadows.
Shot on a professional full-frame camera with an 85mm portrait lens, f/2.8, shallow depth of field, perfectly focused face, high dynamic range, realistic optical rendering.
**VISUAL STYLE:**
Authentic author photography, premium publishing aesthetic, serious nonfiction author branding, understated elegance, natural and believable rather than overly glamorous. Photorealistic, high resolution, professional retouching without altering the person's appearance.
**FRAMING:**
Chest-up portrait, centered composition, head and shoulders fully visible, sufficient space above the head, face occupying approximately 40–50% of the image height. Vertical 4:5 aspect ratio, suitable for author biographies, book covers, Amazon Author Central, and professional websites.
**STRICT NEGATIVE INSTRUCTIONS:**
No identity changes, no face swapping, no altered hairstyle, no artificial skin, no exaggerated muscles, no artificial facial symmetry, no beauty filters, no cartoon effects, no painterly rendering, no text, no watermarks, no logos.
**FINAL REQUIREMENT:** The result must look like a real professional photograph of the exact person in the uploaded reference image, not a similar-looking person.
