Can you control which photos are moved to iCloud Photos?
Under the Apple Support article Set up and use iCloud Photos - Apple Support there is a section headed “Download copies of your photos and videos” that tells you “When you turn on iCloud Photos, your photos and videos automatically upload to iCloud”. Nowhere else in this article is there any info about exactly how this works. Does it really mean ALL photos, anywhere on your device - in this case a MacBook Pro?
Without this information I am hesitating to enable iCloud Photos as I have over 40,000 images stored in over 70 different Photos libraries with much carefully collected metadata added. If anything does not work as I want, I’ll have a huge amount of work to do to unpick the mess. So initially I would like to set up iCloud Photos based on a small Photos library (that would be a copy of one of my libraries so I’ll lose nothing if it all goes wrong). Then I can see if the process is working as I require, and gradually move more of my collection over to Cloud. Is it possible to do this, and if so, how?
