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 transforming the image into a professional linguist/philologist portrait.

TRANSFORMATION DESCRIPTION:
Transform the subject into a thoughtful academic linguist or philologist. The person should appear as if they are in their university office or library, surrounded by books and linguistic materials. Add subtle academic accessories that fit naturally with the person's appearance: round or rectangular wire-rimmed glasses (if suitable for the face shape), a comfortable tweed jacket or cardigan over a collared shirt, and perhaps a small notebook or pen in hand. The expression should be contemplative and intelligent, with a slight, thoughtful gaze. The setting should feel scholarly and cozy, with bookshelves in the background filled with dictionaries, grammar books, and linguistic texts. The overall vibe is that of a dedicated language scholar deeply engaged in their work.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic, cinematic, and professional. The image should look like a high-quality studio portrait or an editorial photo for an academic magazine.
- Lighting conditions: Soft, warm, and natural lighting. Ideally, window light from the side (Rembrandt lighting) to create depth and highlight facial features without harsh shadows. The background should be slightly darker to keep focus on the subject.
- Color palette: Warm, earthy tones (browns, creams, deep greens, burgundy) to evoke a classic academic atmosphere. The clothing should be in muted, sophisticated colors (navy, charcoal, forest green).
- Background treatment: A blurred background of a bookshelf (bokeh effect) or a clear but non-distracting library setting. The books should be visible but not individually detailed, creating texture and context.

TECHNICAL QUALITY PARAMETERS:
- high resolution, 4K, detailed
- sharp focus on face
- professional quality
- Aspect ratio: 2:3 (vertical portrait) or 4:5 for social media compatibility
- High dynamic range (HDR) for rich colors and textures
- Detailed fabric texture on clothing (tweed, wool, cotton)
- Natural skin texture preserved with no plastic smoothing

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted features, unrealistic proportions, blurry face, loss of likeness, cartoonish style, low quality, pixelation, overexposure, underexposure, unnatural skin smoothing, bad anatomy, extra limbs, mutated hands, text on clothing, watermark, signature, low contrast, noisy background, plastic skin, HDR artifacts.
