I think that is exactly what I am looking for. If I understand correctly, the workflow would be to import original to LR Classic, create a collection and sync with LRCC, then open LRCC and upload originals to cloud. I am curious as to why Adobe would not recommend that workflow? It would seem useful (as you say) but also provide back up of the original photos.
A variation that I would like to use as well is when working remotely; import originals to LRCC using a laptop, edit on location, then when back at the desktop, sync with LR Classic. Any thoughts on how to sync with Classic when the original import is in LRCC?
Thank you. This is extremely helpful.
Provided you have the Classic catalog enabled for syncing, ANY image that you add into any of the LRCC apps will automatically be synced down into Classic, full original, and stored in a default location which you can change in the Classic preferences. So, take a picture on your phone, start LRCC on the phone (or better yet, use the LRCC camera on the phone), the image syncs to the cloud. When you next start Classic the image is downloaded automatically. That functionality has been available for about 4 years...
