A few weeks have passed since Apple's iOS 8 preview giving developers plenty of time to dig around and discover new features in the beta. Several sources have found a "Recently Deleted” album in the Camera app. The folder allows users to access their deleted photos and recover images or videos they accidentally deleted.
The ability to hide individual photos was also previously discovered in the Photos app. Users can now tap and hold a thumbnail or image to bring up the "Hide Photo" option. So far you can only keep images hidden from the Moments, Collections and Years albums.
