Match before-and-after site photos from the same viewpoint.
A comparison is easier to read when the camera angle stays similar. Fieldnote lets you use an earlier photo as a translucent guide, then slide between the two visits to inspect the change.
Match the scene, then capture a new original
Open an earlier photo and use its framing guide on a return visit. Align recognizable parts of the scene before capturing the new image. Try to keep the viewpoint and subject coverage consistent so the comparison is useful.
The guide helps with framing; it does not prove that the conditions, lighting or device position are identical. Each new image is a separate original with its own time and GPS reading. Check the new location accuracy just as you would for any capture.
Explain the change in the report
Use the comparison slider to review the pair and add notes that describe the observed difference. A short explanation of the work or the visit helps the recipient interpret a visual change without guessing what happened between photos.
Include before-and-after comparisons in a PDF report alongside notes and capture details. Preserve the original files and keep a backup or exported archive if the record matters beyond the life of the phone. Local storage alone is not a separate backup.
Before you finish
- Choose an earlier image with a clear, repeatable viewpoint.
- Align the new shot using visible features in the scene.
- Keep both originals and explain the observed change.
Questions before you start
Does the guide replace GPS capture?
No. The framing guide helps align the view; each new photo still has its own capture time and location reading.
Can the report include both visits?
Yes. Fieldnote PDF reports can include before-and-after comparisons, notes and capture details.
