Restoring Group Family Photos with AI: What Actually Works (And What Doesn't)

Restoring Group Family Photos with AI: What Actually Works (And What Doesn't)

Group family photos are the hardest for AI to restore - more faces means more things that can go wrong. After 15 iterations of automated testing across 3 different group photo types, here's what we found actually works.

Why AI Photo Restoration Changes Faces (And How to Prevent It)

Why AI Photo Restoration Changes Faces (And How to Prevent It)

AI photo restoration models often alter faces during enhancement. Based on testing 100+ prompt variations across multiple presets, we identified the specific parameters that cause face drift and developed techniques to prevent it.
