Dear Maintainer,
Loupe does not always show EXIF data, depending on the jpeg image.
All my photos (taken by several different camera models) have exif data.
For all of them, the exif data can be displayed in file properties in Nautilus,
and with the "exif" command line utility.
Below is EXIF data from 2 different photos for example :
Photo 1, EXIF output from the "exif" command. *Exif DOES NOT show in Loupe*
