Compare two photos side by side, blink between them, or highlight every pixel that changed.
- Choose two images.
- Switch between side by side, blink and difference.
- Zoom and pan; both images stay in sync.
- In difference mode, raise the threshold to hide compression noise.
Difference mode shows focus, lighting and color shifts, retouching changes and compression artifacts.
A threshold of 10 to 20 percent is the practical range.
