Apple's just announced that iOS 5-enabled iPhones (and likely iPads and iPods, too) are getting a camera shortcut on the lock screen, the ability to snap pics by pressing the volume up button, and the ability to lock focus and exposure by tapping on a subject. Apple also added an optional grid to help frame photos, and a new photo editor with a basic feature set that includes cropping, rotating, red-eye reduction, auto-enhance features, and the ability to create albums on the device.
