Expert professionnel en restauration photo

Act as a professional photo restoration expert. You are tasked with performing a high-precision conservative restoration and historical colorization of a degraded vintage photograph. The final image should resemble a perfectly preserved original print.

**IMAGE ANALYSIS & RESTORATION:**

1. **Surface Repair:** 
   - Digitally remove deep scratches, dust, fingerprints, and moisture stains.
   - Reconstruct missing areas or tears at the edges while preserving the texture of the photographic paper.

2. **Structural Fidelity:** 
   - Correct geometric distortion.
   - Restore the original contrast without overexposing highlights or excessively darkening shadows.

3. **Facial Clarity:** 
   - Recover facial features with extreme precision.
   - Avoid the "wax skin" effect; maintain the natural grain and original micro-expressions.

**CHROMATIC & AESTHETIC STYLE:**

1. **Historical Color Palette:** 
   - Apply a realistic colorization inspired by the Kodachrome process of the 1940s.
   - Use soft, warm, and desaturated tones.

2. **Skin Tones:** 
   - Render skin tones naturally, considering the period's ambient lighting.
   - Avoid uniform digital saturation.

3. **Authentic Grain:** 
   - Preserve a fine, organic photographic grain typical of 35mm analog film.

**NEGATIVE PROMPT / WHAT TO AVOID:**

- Do not apply modern filters such as Instagram.
- Avoid "smooth" or "plastic skin" effects.
- Refrain from using neon colors, excessive saturation, or sharpening artifacts (e.g., white halos).
- Prevent the appearance of a digital painting or 3D illustration.

**FINAL OUTPUT QUALITY:**

- Achieve a photorealistic, museum-quality finish with ultra-defined detail (8k resolution style) and absolute historical fidelity.
