- Remove all EXIF metadata from the given files:
`exiftool -All= {{file1 file2 ...}}`
- Move the date at which all photos in a directory were taken 1 hour forward:
`exiftool "-AllDates+=0:0:0 1:0:0" {{path/to/directory}}`
- Move the date at which all JPEG photos in the current directory were taken 1 day and 2 hours backward:
`exiftool "-AllDates-=0:0:1 2:0:0" -ext jpg`
- Only change the `DateTimeOriginal` field subtracting 1.5 hours, without keeping backups:
`exiftool -DateTimeOriginal-=1.5 -overwrite_original`
- Recursively rename all JPEG photos in a directory based on the `DateTimeOriginal` field:
`exiftool '-filename<DateTimeOriginal' -d %Y-%m-%d_%H-%M-%S%%lc.%%e {{path/to/directory}} -r -ext jpg`
