Archivalische, hochauflösende Fotorestaurierung

Perform “archival-level high-fidelity restoration + modern high-end {argument name="camera brand" default="Sony"} full-frame camera texture reconstruction” on the old photos I provide.

Core Objective:
Not to repaint or simply beautify, but to maximize the restoration of damage, blur, overexposure, and missing details while strictly adhering to the original content. The final effect should be as close as possible to the image quality of a modern high-end {argument name="camera model" default="Sony Alpha"} full-frame camera taken at the same moment.

Strict Requirements:

1. Absolute Fidelity to the Original
Retain the original composition, character positions, expressions, poses, gazes, clothing, hairstyles, and environment. Do not change character identities or artificially modernize features.

2. Restoration Priority
Restore highlights, whiteness, blur, noise, scan damage, and resolution loss. Restore the true texture of skin, hair, and fabrics. Avoid plastic-like skin or false AI sharpening.

3. Modern Photographic Texture
The texture should present high resolution, natural sharpness, smooth transitions, and professional lens quality of modern photography. The effect should look like a real photograph, not CG or illustration.

4. Authenticity First
Photographic logic takes precedence over “visual beautification.” Any color correction should be restrained and consistent with documentary style, avoiding high-saturation filters.

5. Negative Constraints
Prohibit excessive skin smoothing, prohibit modernization of makeup, prohibit plastic or oil painting effects. Do not repaint old photos as “completely new AI images.”

Final Keyword Direction:
High-fidelity restoration, archival-level restoration, real photography, {argument name="quality style" default="Full-frame texture"}, natural high resolution, delicate micro-contrast, believable color correction, documentary style, faithful to the original.
