How do I keep some photos only on my mac and not on my iPhone
I just did a photo slide show for a memorial using hundreds of photos from a friends family and the MacOS photos.app. It turned out great. But, I have iCloud Photo Library turned on and now almost 1000 photos are clogging up my photo stream. I want to have all these photos available on my Mac, in the Photos App so I can replay and re-export the slideshow project if needed. But - I don't want all these photos on my phone. I do still want the benefits of iCloud Photo Library syncing between my Mac and my phone for the photos from before I built the slide show and all the photos I took on my phone since then.
I know I can export the photos into a local folder on my Mac and delete them from the Photo App, but that ruins the slide show project.
I also know I can export the project into a stand alone video file, but the export function is imperfect and the results are not as good as playing the project directly from the Photos App in full screen mode.
What I need is a way to keep a subset of photos from syncing to my phone while still being available in the Photos App without completely turning off iCloud photo library.
Any ideas?
