Comparison of crops of my great-grandmother's eyes from a photo taken in the 1880s.
On the left is original (untouched) and was taken with a basic scanner;
On the right is restored and was taken with a photo restoration studio scanner;
Below was restored and colourised using AI tools, or what the photo restoration studio I go to calls "face-fixing software", and the eyes are vastly improved.
