How do I delete pictures from Camera Roll without deleting them from Photo Stream?

[iMore Question]

I noticed this morning my iPhone 6+ is running low on storage space. I've taken a lot of videos. So...I go to the Camera Roll and start to delete when I'm warned that deleting files from the Camera Roll will also delete them from Photo Stream... which in turn would delete them from all my devices. I don't want to do that! I cannot find a way around this. Help?!

Photo stream isn't considered photo storage, so there's no way to do what you're asking. Your best bet would be to use iCloud photo library instead of photostream.
