What is Metadata?
Metadata- a set of data that describes and gives information about other data.
What is Image Metadata?
– Image metadata is text information pertaining to an image file that is embedded into the file or contained in a separate file that is associated with it. Image metadata includes details relevant to the image itself as well as information about its production.
What is Exif metadata?
– Exif metadata is a record which shows the digital SLR camera settings used to take a particular photograph. This data is recorded into the actual image file. Therefore each photograph has its own unique data
– It shows information like exposure, aperture, the resolution the camera model and GPS coordinates if the image is geotagged.
Why is this important? – Great for forensic analysts (Ethical) and tracking.

- -x : imago will extract EXIF metadata.
- -s: the temporary SQLite database will not be deleted after the processing.
