Remove photos on ONE device only
How do I eliminate photos on one device only? I want to make more space on one iPad by not having ANY photos on it. But I don't want to lose my photos on all of my other iPads, iphone and iMac.
My iCloud settings, under photo options, show all 3 boxes checked: iCloud Photo Library; My Photo Stream; and iCloud Photo sharing. My storage is optimized but even so, I am not actually sure if all my photos 'live' on iCloud or if "Photo Streaming" means that some full sized photos live within the iPad.
What's a good approach?
1. Turn off iCloud Photo Library? If so, I don't understand the phrase 'Photos & videos which have not been fully downloaded will be removed from this iPad. Therefore I don't know which of the two options, a.) Remove from iPad b.) Download Photos & videos to choose.
2. Delete the Photo app?
I am a generally experienced user and yet this aspect of Photos and space seems unduly confusing.
Thanks for any thoughts.
iPad, iOS 9.3.1
