The Camera’s user interface has been completely changed.
Just swipe to change from: video to camera to square and finally to panorama
If you like Instagram, the new square photo option and live filters will be at the top of your favorite iOS 7 features list.
You can apply filters to still and square photos. Pick a filter and see the effect before you take the picture. Or just take the shot and apply it later.
If you ever change your mind and decide that the picture is the best without a filter, you can simply remove it later.
There’s still a quick–access slider on the Lock screen, though now it competes for that gesture with Control Center.
