Scan & Restore Vintage Stereo Cards (Then Remount Them in SPM)
Vintage stereo cards — the twin prints on card stock that parlours viewed through stereoscopes for a century — are fragile, foxed, faded and frequently wonderful. This workflow digitises them properly: scan once, restore honestly, and mount them digitally in StereoPhoto Maker so they can be viewed, printed and shared like new pairs.
1. Scan the whole card, flat
- Scan the entire card including borders at a resolution that survives cropping — the borders carry the caption and dating evidence, which are part of the artefact.
- Keep the card flat and square to the scanner; a skewed scan bakes in rotation error.
- Save the untouched scan as your archival master before any editing.
2. Split and clean each view
Work on copies. Crop the left and right views, then do the conservative repairs: dust and spot removal, gentle level correction for fading. Resist the urge to “improve” the scene — restoration ethics for heritage material means repairing damage, not revising history. Heavy damage (tears across faces, silver mirroring) is where AI restoration earns a test on a copy, never on the master.
3. Align and mount in SPM
- Open the two views as a pair in SPM and run auto alignment — century-old mounting was good, but card warp and scanning add their own errors.
- Set the stereo window as the original publisher would have: subject at the card.
- Save the SBS master; use the Stereo Card Maker to produce a faithful modern reprint card if you want the object back in a viewer.
4. Share with context
Publish the restored pair with its caption, photographer/publisher and approximate date when known. A stereo card’s metadata is half its value; a bare image is a halved artefact.
For copies with serious damage, Topaz Photo handles the restoration heavy lifting (scratches, blur, noise) before SPM aligns the pair.
