The more I research iCloud Photo Stream the more confused I get. This is a really silly question but here it goes... I have a lot of pictures taken on my iPhone (almost 400 pics + about 30 videos) all saved under my Camera Roll. I looked at my iCloud iPhone backup and my camera roll alone is using up 80% of my 5GB limit. Most of the those photos I've taken are also on my Photo Stream so I was thinking, to free up some iCloud storage (since my understanding is that Photo Stream doesn't count towards iCloud storage) I would delete the photos from Camera Roll and leave those in Photo Stream. Is that a safe way to free up some of my iCloud storage? A related question; on my iPhoto app on my Mac it shows my Photo Stream pics from my iPhone there. Are those backed up into my iPhoto library, or do I need to manually add them to my Library?
