A few weeks ago Adobe renamed Lightroom to Lightroom Classic and re-launched Lightroom as cloud connected Lightroom CC. Aside from making everyone really confused, some concerns rose about how will this actually work in terms of licensing Lightroom (just see some of the comments on this post). As most things Adobe, everyone will probably migrate to the new Lightroom CC given enough time, but if you want to keep your Lightroom Classic installation and still be able to sync across multiple devices, Dan Watson has a solution for you.
The secret lies in combining two of the new Lightroom features: Lightroom mobile and Smart Previews.
The other trick is to make a collection inside a catalog and mark this collection as “sync with Lightroom CC”. Now, only images that go inside this catalog will sync with the other computers. The nice thing is that not the BIG raw files will get synced, but the significantly smaller Smart Previews. On the other hand, these Smart Previews can be exported to a decent size jpg. The bonus? You dont need to move to the new Lightroom, and can keep your standalone installation. [Sync Lightroom Catalogs & Images Across All Your Devices | Dan Watson, h/p Pratik Naik for the tip]
