From matching points to a dimensioned PDF

Work with both views
Import ordered photos, two image files, or one side-by-side image. Inspect a common crop inside both sources.

Choose corresponding features
A and B solve scale, rotation and translation. A separate Check point measures remaining vertical mismatch.

Use your print dimensions
Set card size, image width and center spacing. Save presets and print the PDF at 100% scale.
Seven real files per delivery
Aligned left and right PNGs, a red-cyan PNG, parallel and crossed pair PNGs, a stereo-card PDF and a JSON recipe. Preview or share actual files. Reopen editable local projects and source-bearing project copies.
Use existing stereo viewpoints. Pairglass does not synthesize depth, capture photos, auto-match features or create spatial HEIC. Red-cyan viewing requires matching glasses; parallel or crossed viewing needs an appropriate method. Working copies have a maximum long edge of 3200 pixels.
