There is probably not enough cloud space to put your entire catalog online and it would be very slow. The sync process is for more initial editing of the most recent photoshoot, with the rest of editing happening on your desktop.
I have two desktops, and put my catalog and recent photos on a USB-attached drive, and back that up to another USB-attached drive, in case I lose or destroy my external drive.
Thanks for the reply!
My issue is that I have a large volume of photos to process. I rank them and then process the selects. My wife often helps with the ranking, and I do all the processing. For me/us, using a tablet to do the ranking (and some edits if that part of the app ends up being nice) would be a huge efficiency improvement, because right now we're stuck using one computer for all the work, and we're not always in front of that computer.
I don't REALLY need my whole catalog, although that would be a great feature. Because I'm using the Mobile feature to edit new photos, all really need it to do is automatically pull all new imports. (Honestly, it's more work than I'm willing to do to maintain a manual set of collections.)
So it would seem there's no way to make Lightroom do a mobile sync with all your photos. Does anyone automate Lightroom? Is there a way to at least have it add newly-imported photos automatically? I'm not above a little scripting, especially if the alternative is to start to work more outside of Lightroom.
