I don’t want everything synced
In general I like the convenience of iCloud Photo Library, but I’m getting very close to the 5GB limit and I don’t know if I like it enough to start paying monthly for the privilege. A lot of my photos are just temporary scans of paperwork that I photograph on my digital camera for printing out. I don’t need these synced to my iPad, but they currently take up about 30% of my iCloud allotment. Is there a way to flag some images as ‘not for syncing’? David Pierce
You can’t flag individual pictures in the Photos app, but you could create a separate library for them. If you start Photos with å held, you’ll see the option to create a new library (or switch library, once you have created another). This new library won’t sync with iCloud (unless you click Preferences > Use as System Photo Library, to select this one instead of the default library) but it’ll otherwise work just the same. When you want to import some scanned documents you just start Photos with å held. Then import your scans to this completely self-contained library, print them out if you want, and finally use the same technique to restart Photos again and switch back to your usual library with all your actual photos in it. This should allow you to stay under the 5GB limit for a little longer.
You can choose which library – only ever the one designated as the System Photo Library – is synced to iCloud.
