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.

Note: This sample will not deliver any camera output on the iOS simulator.
