The File - IPTC Profile Manager command allows you to create and modify IPTC profiles, which can then be assigned to one or more photos.
This is possible in two ways:
1. when editing the metadata
2. directly when adding the photos when importing a new folder or synchronizing.
If you use IPTC profiles to fill the metadata, it is easier to update the data later by simply changing the IPTC profile. All changes are automatically applied to the images that have the corresponding IPTC profile assigned.
