ARE PHOTO STREAM & CAMERA ROLL GONE FOR GOOD?
The quick answer is, not really. All images from your Camera Roll and Photo Stream are now stored in one big folder called All Photos. But here's where it gets a little confusing. For now, you can still use Photo Stream to sync your 1,000 most recent photos or ones taken in the last 30 days without counting against your iCloud storage.
While a bit redundant, there are a few reasons you might want to keep Photo Stream enabled. While it's rumored that Apple will phase out Photo Stream this year when Apple releases a new Photos app for Mac, for now, it's useful if you use iPhoto on your Mac or PC and you want your recent photos to continue to sync, or if you have an older device not running iOS 8.1 or later. For best results, turn on both iCloud Photo Library and Photo Stream so you can access your shots via iPhoto or Aperture.
