I have a series of saved identity plates in a LC library:
1. Where are these saved? Can I edit them outside of Lightroom (it would be easier to work with them).
2. I exported the library to move it to a different disk and the saved identity plates seem not to have been included
1. AFAIK, Identity Plate templates are only stored within the catalog itself, and are therefore not accessible for editing outside LrC.
2. From a quick test, the "Export as Catalog" function does NOT export any saved ID Plate templates. If you need to move a catalog to a different drive, it would be far simpler to copy the catalog folder to the new drive and open it from there. That should retain all the saved ID Plate templates.
