For the life of me, I cannot figure out how to properly manage photos on my iPhone and Mac. Every photo I take ends up appearing my iOS Photos app twice, one of which is deletable, and the other which is not. From what I gather, I can delete only one of them because that is in my Camera Roll. The other one, apparently, I must delete from my computer. With the 6s now, though, the only one I can delete is the Live Photos version, which would just leave a simple .jpg. I had My Photo Stream turned on, but turned that off. I don't have the iCloud Photo Library turned on. What do I have to do to stop getting all of these duplicate photos? What other information can I provide to help you help me?
