iCloud photos upload
Hi there
I'm a bit confused about where my photographs are stored and how to free up space on my iPhone. I subscribe to extra iCloud storage space and have activated automatic upload of my photo library. I have also chosen 'Optimize iPhone Storage' and have got the photo stream switched on.
When i set all of this up, I was under the impression that any photographs taken on my iPhone would automatically be stored in my iCloud, not on my iPhone. However, the photographs and videos are still taking up a huge amount of space on my phone, and I am unsure of whether to delete them as i don't know whether they are uploaded or not.
Can anyone shed any light on how this works, and how i can safely free up space on my iPhone?
Thanks!
iPhone 5s, iOS 8.4.1
