So when I turn on iCloud Photo Library will it put all the photos on my iPhone in the library or just the ones in the Camera roll? WHen I turned it on, on my iPad it removed most of the photos that were there and only kept the photos from the roll. I do not want to lose any photos. I want everything from my collection to be backed up. If I look at album son my phone it shows 83 in Camera Roll and 740 in My Photo Stream.
