Changelog
A chronological record of new features, restoration pipeline upgrades, and quality improvements shipped to SepiaFoto.
Core Restoration Pipeline V2 & Touch-Interactive Slider
Major restoration engine upgrade addressing Kodak dye fade and yellow cast, authentic film tone contrast curves, pointer-captured touch comparison slider, and verified public domain historical benchmarking.
Core Restoration Pipeline V2: Auto White Balance & Dye Fade Reversal
Overcomes typical color shifts in vintage 1960s-1980s Kodak prints. A dedicated pre-processing stage applies adaptive RGB histogram percentile clipping (0.5%–99.5%) to neutralize pervasive yellow and cyan fog, recovering crisp whites on clothing and curtains before neural inference.
Filmic Tone Mapping & S-Curve Contrast Optimization
Implemented calibrated post-processing with zero-level black point anchoring and gentle S-curve film tone mapping. Eliminates the milky, washed-out veil common on aged paper scans while preserving authentic grain structure without blur or smudge artifacts.
Calibrated CodeFormer Facial Enhancement (0.65 Target)
Fine-tuned blind face enhancement parameters to prevent artificial over-smoothing. Eye clarity, facial symmetry, and skin texture are restored with sharp definition while retaining authentic family resemblance and vintage photograph character.
Interactive Touch & Pointer-Capture Comparison Slider
Completely overhauled the Before/After comparison tool. Users on mobile devices and desktop browsers can now directly grab and drag the center handle or photo horizontally. Implemented full pointer capture and touch-none gesture isolation to eliminate page scrolling interference.
100% CC0 Public Domain Museum Archive Benchmarks
Standardized all public showcase examples on authentic Library of Congress glass plate negatives and historical prints (1863 Lincoln, 1922 Edison, 1875 Glass Plate), adhering to strict personal privacy standards and zero-cost public domain compliance.
Multi-Language Localization & Automated Privacy Deletion
Expanded SepiaFoto globally across 4 languages with localized guides, free watermarked previews, and a strict 24-hour physical file purge policy.
