Capturing High Resolution Photos

I got a tip from a subscriber about the method I used to capture the photo in the last episode. Since we're capturing the data using the preset we chose for processing the rectangles, we are bound to that preset when we export to an actual photo. By using AVCapturePhotoOutput, we can have much more control over the format, size, and quality of the resulting image. In addition, since we are leveraging the SDK for capturing the photo, we benefit from things like auto-flash, HDR, auto focus, and the built-in camera shutter sound. (Yay for deleting code!) The end result might not look very different on device, but if you are taking that image somewhere else to do OCR or other processing on it, a higher quality image is important.
