deleting photos after uploading to iCloud
after my photos and videos have been uploaded to iCloud can i delete them off my iPhone and iPad? I use the latest iOS and Photos software with the option to save all photos to the cloud.
I use an iMac , iPhone 6+, Ipad all using the latest iOS and OS X and back up via iTunes to the cloud and back up photos app to the cloud
after backing up i observe i.e. on my phone that i still am using nearly 4GB for photos and i want to save space on my phone.
I have set the photos optimisation setting on my phone. IE lower quality copies kept on the phone.
Is there a way i can just have photos on the cloud once synced?
