Adjust capture time across cameras

Use Adjust Capture Time… in ⌘K, or press ⌥⌘T while browsing files. The sheet lists detected cameras, distinguishing serial numbers when available, and the photo count for each.

1. Compare photographs of the same clock or event to work out each camera’s correction.
2. Enter a signed offset beside that camera: +1h, -90s, or +2m30s. Leave a camera at zero to keep its times.
3. Review the camera counts and the number of files on the write button before applying.

The scope is all loaded photos for each camera with a nonzero offset, not only your selection. Open the intended folder scope first. This is a metadata write for writable files; import card originals before adjusting them. The job’s Shoot date used in naming is separate and does not rewrite capture timestamps.
