Import from MacDive / UDDF

Import dives

On desktop, open Logbook → Import and choose a UDDF file (MacDive and
most dive apps can export UDDF). Dives, samples and sites are matched and loaded;
re-importing the same file is safe — duplicates are skipped.

Auto-add photos

Use Logbook → 📷 Auto-add photos to match a batch of images to the right
dive by their EXIF time:

• Drag-and-drop works for a handful of photos (~30 at a time).
• For a whole trip, use Pick a folder, or export from your Photos app to a
  folder first and drag that folder in.
• Only photos whose time matches a dive (±30 min) are imported — the rest are
  reported as unmatched, never placed on the wrong dive.

The time offset control is only needed if your camera clock itself was wrong.
