EXIF data contains a thumbnail (8551 bytes).

Since, this file contains a thumbnail, we can extract it like this.

┌─[user@parrot][~/Desktop]
└──╼ $exif waterfall.jpg -e
Wrote file 'waterfall.jpg.modified.jpeg'.

And I can grep for the camera model like this.

localhost% exif lake-albert.jpg | grep Model
Model               |DMC-FT2

This is very useful when downloading a photo from the Internet and it could contain useful information.
