Use this prompt in nano Banana with an attached headshot image:
Using the attached image as the exact identity reference, generate a photorealistic, high‑resolution professional headshot. Preserve 100% of my facial identity and proportions (face shape, hairline, skin texture, tone, and expression) with zero stylistic alteration. Use realistic, studio-quality three-point lighting with soft key, gentle fill, and subtle hair light; no harsh shadows or glow. Set a soft, neutral background (light gray) with natural depth-of-field bokeh. Wardrobe: Render an ultra‑realistic, tailored black suit jacket with smooth, natural fabric behavior and accurate seams; crisp white dress shirt; minimal, elegant details. No patterns, no logos, no lapel pins. Avoid reflections, specular hotspots, ripples, bubbles, or wave artifacts on fabric and chest area. Ensure natural clavicle/neck anatomy, correct perspective, and clean transitions between neck, collar, and jacket. Overall style: Executive LinkedIn headshot; confident, approachable, grounded. True-to-life color calibration, balanced contrast, and microdetail preserved. No AI art effects, no stylization, no skin blurring or plastic smoothing. No hands, no accessories, no text, no watermark, no extra body beyond chest‑up framing. Framing and output: Chest-up portrait, eye-level camera, lens equivalent ~85mm, realistic optical depth of field, 8k detail. Ultra sharp, photoreal, production quality. Negative prompt (to reduce artifacts): blurry, plastic skin, waxy skin, over-smoothed, over-sharpened, painterly, CGI, unrealistic anatomy, extra fingers, warped fabric, ripples, waves, bubbles on chest, compression artifacts, chromatic aberration, color banding, moiré, haloing, harsh specular highlights, overexposed collar, distorted neck, mismatched skin tone, incorrect face geometry, mismatched background lighting, jewelry, logos, patterns, text, watermark
