5-Step Workflow

Load old photo

• a) Upload from file
• b) Open GhostViewer (GV) map (new tab)
• c) Import from Geograph

Add new photo

• Use Photo Library, Take Photo, Choose File, or Ghost Guide Camera

Match landmarks

• Click matching points on both photos
• Use at least 4 points (6-8 spread across the image is better)

Align images

• Click Align Images
• Try Similarity, Affine, or Perspective if needed

Review and output

• Check alignment quality
• Adjust points/mode and re-align if required
• Save project if signed in

Tips for Best Results

• Use corners + center landmarks, not clustered points.
• Crop/straighten photos before matching if lines look tilted.
• Keep the same camera angle and distance where possible.
• For strong viewpoint differences, try Perspective mode.

Geograph Quick Notes

• Location is required, keyword is optional.
• You can use current location.
• Keep source attribution when reusing Geograph images.
