iOS 7 comes with new Camera and Photos app
The new Camera app in iOS 7 now features a new square shooting mode for Instagram shots. The photos you take will then get automatically sorted in the Photos application and not just dumped into the camera roll.
This all happens in a new “moments” organization tool creating logical events and grouping photos by criteria such as the date when images were captured.
Of course all of this is fully integrated with iCloud - AirDrop allows you to share with nearby devices and is built in, and you can share onto other people’s streams. The interface also now fits the new simplistic and clean motif of iOS 7.
