Before and after pairs

A before-and-after is a claim about a change. Trace stores that claim explicitly rather than leaving two photographs near each other in a feed and hoping.

Pairing

In the app, shoot the before and tag it, do the work, then shoot the after from the same position and pair them. In the office, open a job, select two photos, and pair them from the selection bar.

In reports

The Before / after report template lays each pair side by side with both timestamps. That is what makes it evidence rather than marketing — the two dates are the argument.
