Composite Tags

The values of the composite tags are Derived From the values of other tags. These are convenience tags which are calculated after all other information is extracted. Only a few of these tags are writable directly, the others are changed by writing the corresponding Derived From tags. User-defined Composite tags, also useful for custom-formatting of tag values, may created via the ExifTool configuration file.
