Alastair: Yes, Lightroom will save the Develop module editing parameters and any IPTC data (including keywords) into the original files or sidecars if you use the "Metadata->Save Metadata to file" command. However, you lose the editing history ... it only saves the parameters ... and the inclusion into collections as well as any Virtual Copies you might have made.
To keep these things intact, the only way to go is to "Import from Collection", which reads one database file into another and preserves ALL information. -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
