There are occasions where you want to set the file dates of a series of files starting from a specific date and steadily increasing from there in constant increments.

A specific example is when you have image files without content creation meta-data, but where you know both the approximate time and the sequence in which they were taken. This is a common scenario especially when you want to import scanned image files into an image management system such as Apple’s Photos or Adobe’s Lightroom.

A Better Finder Attributes enables you to do this:

  • select Advanced date manipulation from the Action: popup menu.

  • select Specific Date from the Use: popup menu.

  • select Increment by sort order from the Change: popup menu.

You can then adjust the sort order and the interval to be used by adjusting the First: and Then: popup menus, and the Hours, Minutes, Seconds, Days, Months & Years input fields. The file list previews the resulting date for every file in the chosen order, so adjust the sort order until the sequence is right, then click Perform Changes.

To write the result into the photos themselves rather than only into the file dates, choose the image and movie destination fields below the Overwrite: checkboxes; see setting the shooting date.
