EXIF stands for Exchangeable image file format, set out by the Camera & Imaging Products Association (CIPA). Full (one hundred and ninety pages) details of EXIF standards and tags can be found in this document.
Wikipedia has a useful page here.
While there are standard tags set out by the CIPA many manufacturers also have or substitute their own.
Queens University, Canada has several useful pages on EXIF tags:
HOWTO: COPY: EXIF Data
While a programme like Eye of GNOME graphics viewer program will allow you to view an images EXIF information it does not give a convenient way to copy the said data.
An easier way to do this is through the terminal:
Terminal:~$ sudo aptitude install exif exiftool
After installation run exif on the desired file:
Terminal:~$ exif /home/user/Pictures/example.jpg
You will then be able to copy the output.
HOWTO: DELETE: EXIF Data
Terminal:~$ sudo aptitude install exiftool
To remove EXIF data in your terminal browse to the folder your pictures are stored in.
To remove EXIF data from a single file:
Terminal:~$ exiftool -all= example.jpg
To remove EXIF data from all files within a folder:
Terminal:~$ for i in *.jpg; do echo "Processing $i"; exiftool -all= "$i"; done
To remove a specific EXIF data field (in this the geo/GPS location field) on individual or multiple files:
Terminal:~$ exiftool -geotag= example.jpg for i in *.jpg; do echo "Processing $i"; exiftool -geotag= "$i"; done
NOTE: Tags can vary by manufacturer so your mileage may vary.
