Get accessor returns the tag value if the tag is present in the metadata tree, or null otherwise.
Set accessor replaces the current tag value if the tag is present in the metadata tree, adds the tag if it was not present, or deletes the tag if a null value is passed.
See the EXIF 2.2 specification for tag usage details.
