Quick wiping of picture metada

img_metadata.md

Removing most identifiable metada (geodata, make and model of the camera):

A short reminder on useful exiftool commands.

for i in *.jpg; do echo "dealing with $i"; exiftool -geotag= -make= -model= -software= "$i"; done without using wildcards.
Or to use wildcards: exiftool -geotag= -make= -model= *.jpg *.jpeg *.JPEG

Doing it on directly on a entire directory:

exiftool -geotag= -make= -model= SOME_DIRECTORY

Doing it recursively on subdirectories too:

exiftool -r -geotag= -make= -model= SOME_DIRECTORY

Adding a -r option allows to recursively process subdirectories. This will process any type of file that is writable by ExifTool, but if you only want to process jpeg images, add "-ext jpg" and maybe "-ext jpeg" (ext is not case sensitive), as in:
exiftool -r -geotag= -make= -model= -software= -ext jpg -ext jpeg SOME_DIRECTORY

Watch out

Some cameras may store more easily identfiable data in other EXIF tags (gps=). Also, by default exiftool will create copies and leave originals untouched. So either make sure to sare the copies or to delete the originals. Or use exiftool's -overwrite_original option to avoid this.

exiftool -r -overwrite_original -P -geotag= -make= -model= -software= -ext jpg -ext jpeg *

-P to preserve date/time of original file(s)
