Archive/set some photos in Photos.app not to be synced with iCloud Photo Library

I want to use iCloud Photo Library just to get photos I take on my phone to my computer. My Photo Stream would work fine if it was reliable. Now I have more than 5GB of photos so I have to pay at least $1 a month just to sync photos unless there is a way to download only or archive some photos not to be synced with iCloud Photo Library (yet still viewable in the app).
