How do I edit RAW in Photos on iOS 10? In Photos on macOS it is clear when I am editing a RAW file:


I need to explicitly choose Image > Use RAW as Original, and 
the type of the file (e.g., Raw vs JPEG) is clearly indicated in several places in the UI.


However Photos in iOS 10 lacks both these features.

How can I be sure I'm editing RAW in Photos on iOS 10?
You will need to use an app from the App Store in order to both take photos in RAW as well as edit them. The two apps I am familiar with that do this are Adobe Lightroom and Obscura Camera.
