IDENTITY PRESERVATION INSTRUCTION: Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while applying the professor transformation. Maintain the original facial identity, expressions, and distinctive marks without altering the fundamental appearance.

TRANSFORMATION DESCRIPTION: Transform the subject into a distinguished university professor wearing academic attire. Add professional eyeglasses with subtle frames, a classic tweed blazer or academic jacket over a button-down shirt or blouse. Style hair in a neat, professional manner appropriate for academia. The overall appearance should convey wisdom, authority, and approachability - a perfect representation of a tenured professor or academic researcher.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic portrait photography with professional studio quality
- Lighting: Soft, directional studio lighting with gentle key light from 45-degree angle, subtle rim lighting to separate subject from background
- Color palette: Warm, earthy academic tones - deep browns, burgundy, forest green, cream, and muted gold accents
- Mood: Professional, scholarly, confident, and approachable
- Background: University library setting with bookshelves, or a warm, blurred academic office with wooden furniture and soft ambient light
- Clothing details: Tweed or wool blazer with elbow patches, crisp button-down shirt, optional tie or scarf, professional glasses with anti-reflective coating visible
- Texture: High-quality fabric textures on blazer, realistic hair strands, natural skin pores and texture preservation

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and eyes
- Professional quality portrait photography
- Aspect ratio: 1:1 for social media, or 4:5 for professional headshots
- Natural skin texture preserved with realistic pores and subtle imperfections
- Cinematic depth of field with background slightly blurred (f/2.8 equivalent)
- Professional color grading with balanced whites and warm undertones

NEGATIVE PROMPT GUIDANCE: Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, poorly rendered glasses, unnatural clothing fit, cartoonish appearance, low resolution, pixelation, overexposed highlights, harsh shadows, plastic skin texture, asymmetrical eyes, mismatched eye color, unnatural skin tone changes, clothing that doesn't integrate naturally with the body, glasses that appear floating or disconnected
