There's no selective sync at this time, but LR iOS is really smart about what it downloads to the phone. I've got 600GB+ in the cloud, and yet it's only taking up 1GB on space on my phone.
I had the same question and I believe I have an answer for you. In the desktop application, after importing, the photos seem to automatically go into "All Synced Photographs", which appears in the Catalog view in the top left (above Collections & Folders). To stop them from syncing:
In the Library view, click on "All Synced Photographs". Use the filter bar to filter the dates that you just imported (or however else you wish to filter). Select the photos you do not wish to sync, right-click on one of them and select "Remove from All Synced Photographs".
This did the trick for me.
I hope that in the future, Adobe will provide an option within the Import dialog to allow users to select whether their photos automatically sync or not.
That removes them from the cloud Richie... and from Lightroom CC. That's ok if you're using Lightroom Classic as your main base, but not a good plan if you're only using Lightroom CC.
Yes it does (or stops them from going there in the first place).
I guess it depends if the OP is using LR Classic CC or LR CC on their computer. It is not clear in the post. Also, OP are you trying to limit what gets synced from your computer to the cloud in the first place (hence to your iPhone) or just what is synced from cloud to your iPhone?
Btw thanks for all your LR resources Victoria - I've read quite a few of your articles and have had your LR Keyboard Shortcuts pdf on my bookmarks bar for over a year now :-)
Thanks Richie. The new LR Classic book is out now, and the LRCC one is a few weeks away from release too.
