Old Photo Restoration

SUBJECT Identity Lock: Absolute preservation of facial geometry and body proportions; Identity Similarity Threshold $\ge 0.95$. Epidermal Fidelity: Execute macro-level epidermal texture synthesis to avoid "plastic" smoothing. Restore natural material skin-pore structures, textile weaves, and era-specific surfaces. Classification & Damage: Autonomous Origin Detection (Real/Synthetic/Ambiguous). Apply DamageScore (0–100) and RegionConfidence (RC). RC $\ge 70$: Context-guided high-detail reconstruction. RC 30–69: Coarse-to-medium structural restoration; zero semantic invention. RC $< 30$: Era-consistent silhouette/texture fill only. Safe Reconstruction Logic: Area-based constraints: $< 10\%$ (Guided inpainting), $10\text{--}40\%$ (Structural geometry synthesis), $> 40\%$ (Texture-only pass). COMPOSITION Frame Integrity: Strict adherence to original aspect ratio, framing, and semantic positioning. No object injection or removal. Perspective & Scale: Enforce rigorous vanishing point alignment and geometric continuity. Spatial Physics: Validate structural synthesis against surrounding geometry to ensure physical plausibility. Revert to "Safe Fill" if PhysicsCheck fails. LIGHTING Global Illumination: Restore Chiaroscuro-level lighting depth while maintaining consistent shadow direction and luminance gradients. Material Reflectance: Physically accurate reconstruction of light interaction with surfaces (specular highlights, matte finishes). Chromatic Consistency: Restore faded tones to era-correct palettes with modern High Dynamic Range (HDR). Maintain vintage warmth/analog character through spectral-aware color fidelity. TECHNICAL SPECS Restoration Pipeline: Sub-pixel deconvolution, motion-blur neutralization, and chromatic aberration correction. Super-Resolution: Execute Multi-stage 4x+ Super-Resolution with an anti-artifact refinement pass. Noise Management: Intelligent separation of sensor noise vs. compression artifacts; preserve original analog grain structure while removing degradational "noise." Output Parameters: Lossless 16-bit PNG/TIFF; Archival and sRGB color space integration; Metadata/EXIF preservation. Zero watermarks/logos/identifying marks altered. 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.
