Photo adjustments were introduced in iOS 15. This feature enables the user to change or modify the capture time and the location for which the pictures was taken. When a user adjusts a photo, the original EXIF data persists, however the Photos.sqlite is updated for some values to show the original timestamp and the adjusted. As we will see in the upcoming slides, the timestamp that the photo was adjusted to will have the seconds zeroed out.

In regard to the iOS device gallery, the photo will show the location and timestamp for which it was adjusted. The original timestamp and location will not be visible to the user. If the photo syncs to iCloud, the adjusted timestamp and location will be used, and the image will be stored with that metadata.

The new few slides will walk you through the logic behind Ian Whiffin’s blog, which were validated by Heather Mahalik.¹
