Restauration de Photo Ancienne en Portrait DSLR

Restore the old reference photo into a professional portrait with DSLR-quality color and detail, styled as if captured with a Canon EOS R6 Mark II. Retain the exact facial features, likeness, and natural expression of the subject. Enhance clarity with authentic skin texture, sharp eye details, and lifelike depth, removing grain, blur, and color fading while avoiding an overly smoothed or artificial appearance.
