Splitting Scans

Winder finds the dark divider between the two photographs in a half-frame scan and proposes a cut. You approve every scan before anything is saved.

Review the cut

• Drag the divider when the proposed cut needs a nudge.
• Rotate either frame until it is upright.
• Keep both frames, keep one, or discard the scan.
• Use Auto-straighten with Pro to orient a whole batch.

The preview stays quick while you work; Winder applies your choices to the full-size scan when you finish.

If the divider is missed

Dark or unusual scans can hide the divider. Winder starts from the center and waits for your review. Move the cut until both frames look right—your original scan is never changed.
