A methodology for keeping Lightrom in sync on several computers:
A Master Catalog liveson Desktop Computer
A Duplicate Copy of this catalog is copied to the Laptop
Changes made on the Laptop can be exported as catalog and imported into the Desktop computer's version of the Master Catalog
1. Create Smart Collection for the date of the last Sync between catalogs using "Edited after [date]"
2. Copy the Master Catalog to the Laptop
3. Do work to the Laptop version of the Master Catalog
4. Select all images in the "Edited After [date]" Smart Collection and export a temporary "Transfger Catalog"
5. Confirm that none of these images have been edited since last sync on the Desktop's Master Catalog
6. Import Transfer Catalog into the Desktop's Master Catalog
