I exported a folder I was working on in LR to a catalog so I could work on it while traveling. I'd like to "sync" it up with the original folder in LR without loosing the edits done while traveling. I could just go off the catalog I created for traveling, but would like to pull it back into the original catalog. Any suggestions?
You can go to File menu within the main original catalog and choose the option to Import from Another Catalog to get that travelling catalog images into this one.
