Professional photo restoration expert

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.
