High-Fidelity Archival Photo Restoration

Perform "archival-grade high-fidelity restoration + modern high-end Sony full-frame camera texture reconstruction" on the old photo I provided. Core goal: Not to redraw it or simply beautify/renovate it, but to maximize the repair of damage, blurriness, overexposure, and missing details in the old photo while strictly adhering to the original content, making the final effect as close as possible to what a modern high-end Sony Alpha full-frame camera would produce in terms of clarity, layers, texture, and authentic photographic effect. Restoration should focus on "recovery" and "reconstruction of real details" rather than "drawing another one based on the original." The background should retain reasonable layering. Overall keyword direction: high-fidelity restoration, archival-grade restoration, authentic photography, Sony Alpha full-frame texture, natural high resolution, authentic micro-contrast, delicate layers, credible coloring, documentary, restrained, faithful to the original. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
