**IDENTITY PRESERVATION INSTRUCTION** (CRITICAL!)
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming the appearance into a Renaissance-era scientist portrait. Maintain the original facial structure, expressions, and identifying marks to ensure the person remains clearly recognizable.

**TRANSFORMATION DESCRIPTION**
Transform the subject into a scholarly scientist from the Renaissance period (15th-16th century). Apply period-appropriate clothing including a dark velvet doublet, a high-collared white chemise with ruffled cuffs, and a scholarly cloak or robe. Add authentic Renaissance accessories such as a leather-bound book, quill pen, or small scientific instrument (astrolabe, magnifying glass, or compass). The hairstyle should be appropriate to the era-short, neatly styled hair, possibly with a hint of curl, or a scholarly cap. The overall appearance should convey intellectual depth, curiosity, and the scholarly atmosphere of the Renaissance.

**STYLE AND AESTHETIC PARAMETERS**
- Art style: Photorealistic oil painting style reminiscent of Renaissance masters like Leonardo da Vinci or Albrecht Dürer, with visible brushwork texture and rich color depth
- Lighting conditions: Dramatic chiaroscuro lighting with a single strong light source (candlelight or window light) creating deep shadows and soft highlights on the face, typical of Renaissance portraiture
- Color palette: Warm, earthy tones with deep burgundies, forest greens, rich browns, and creamy whites; muted gold accents; warm skin tones with natural transitions
- Background treatment: Dark, textured background resembling aged wood paneling or stone wall of a study/library; subtle atmospheric depth with soft vignette; no modern elements
- Facial expression: Thoughtful, contemplative, with a slight scholarly intensity; eyes focused as if examining something closely
- Texture details: Visible fabric texture on velvet clothing, leather book covers, parchment paper quality, natural skin pores and subtle imperfections for authenticity

**TECHNICAL QUALITY PARAMETERS**
- High resolution, 4K, detailed
- Sharp focus on face with natural depth of field
- Professional quality portrait photography standards
- Aspect ratio: 4:5 or 3:4 vertical portrait orientation (suitable for classic portrait framing)
- Natural skin texture preservation with Renaissance-era softening effect
- Rich color depth with subtle film grain or canvas texture overlay
- Detailed fabric rendering showing velvet nap and linen weave

**NEGATIVE PROMPT GUIDANCE**
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, modern clothing elements, anachronistic accessories, plastic or synthetic fabric textures, overly smooth or airbrushed skin, garish colors, flat lighting, cartoonish or anime style, low resolution, pixelated details, unnatural skin tones, mismatched lighting on face and clothing, visible seams or clothing artifacts, overly sharp digital edges
