### SquareCam ###
SquareCam demonstrates improvements to the AVCaptureStillImageOutput class in iOS 5, highlighting the following features:
- KVO observation of the @"capturingStillImage" property to know when to perform an animation
- Use of setVideoScaleAndCropFactor: to achieve a "digital zoom" effect on captured images
- Switching between front and back cameras while showing a real-time preview
- Integrating with CoreImage's new CIFaceDetector to find faces in a real-time VideoDataOutput, as well as in a captured still image.
Found faces are indicated with a red square.
- Overlaid square is rotated appropriately for the 4 supported device rotations.
Xcode 4.2 or later; iPhone iOS SDK 5.0 or later.
iOS 5.0 or later. This app will not deliver any camera output on the iOS simulator.
