The camera functionality in the iPhone has always been one of my most used features. iOS5 brings some enhancements, which are listed below:
Camera improvements
- Double-click the Home button when device is asleep to bring up a camera shortcut on iPhone 4S, iPhone 4, iPhone 3GS and iPod touch (4th generation)
- Volume Up button to take a picture
- Optional grid lines to line up shots
- Pinch to zoom in the preview screen
- Swipe to camera roll from preview screen
- Tap and hold to lock focus and exposure; iPad 2 and iPod touch (4th generation) only support exposure lock
Photo improvements
- Crop and rotate
- Red-eye removal
- One-tap enhance
- Organise photos into albums
This list was taken from the official release notes, which were accessible via iTunes pre-installation.
