Per tal de modificar les metadades d'una fotografia podem utilitzar: EXIFTool

Per fer-ho podem utilitzar l'eina per linia de comandes:

ExifTool by Phil Harvey.

Download the Image-ExifTool distribution from the ExifTool home page
(The file you download will have a name like "Image-ExifTool-#.##.tar.gz".)
Unpack the distribution and make it your current directory by typing:
```
cd 
gzip -dc Image-ExifTool-#.##.tar.gz | tar -xf -
cd Image-ExifTool-#.##
```
where "#.##" is the version number of the ExifTool you downloaded.
(At this point you may run exiftool by typing "exiftool ".)

Test and install ExifTool by typing:

perl Makefile.PL
make test
sudo make install

Una vegada instalat podem probar a posar un any menys a la data de creació:

 sudo exiftool -DateTimeOriginal-='1:0:0 0:00:0' directori

Per més canvis:

man exiftool

No cal preocupar-se per les fotos originals, ja que les reanomena.
