|I want to start using Lightroom. I have 2 PCs at different locations.||Will I be able to store my photos / Lightroom editing metadata on an external drive and rotate between the two computers?|
Yes but you will be needing to keep the catalog and the original image on the external drive.
Lightroom catalog stores the information about what images you have imported in Lightroom as well as what edits you have done on the images, tags, keywords etc.
By default the catalog is saved in the pictures folder of the computer inside Lightroom folder.
Thanks, good to know. How about between a PC and an iMac?
well the catalog remains the same for mac and pc
