     An NSData of floats describing the camera lens' radial distortions.
  
  @discussion
-    Images captured by a camera are geometrically warped by radial distortions in the lens. In order to project from the 2D image plane back into the 3D world, the images must be distortion corrected, or made rectilinear. Lens distortion is modeled using a one-dimensional lookup table of 32-bit float values evenly distributed along a radius from the center of the distortion to the farthest corner, with each value representing an elongation or compression of the radius (1.0 for any given point indicates no elongation). This model assumes radially symmetric lens distortion. When dealing with AVDepthData, the disparity / depth map representations are geometrically distorted to align with images produced by the camera. For more information, see the reference implementation below.

+    Each time you access this method, AVCapturePhoto generates a new CGImageRef. When backed by a compressed container (such as HEIC), the CGImageRepresentation is decoded lazily as needed. When backed by an uncompressed format such as BGRA, it is copied into a separate backing buffer whose lifetime is not tied to that of the AVCapturePhoto. For a 12 megapixel image, a BGRA CGImage represents ~48 megabytes per call. If you only intend to use the CGImage for on-screen rendering, use the previewCGImageRepresentation instead. Note that the physical rotation of the CGImageRef matches that of the main image. Exif orientation has not been applied. If you wish to apply rotation when working with UIImage, you can do so by querying the photo's metadata[kCGImagePropertyOrientation] value, and passing it as the orientation parameter to +[UIImage imageWithCGImage:scale:orientation:]. RAW images always return a CGImageRepresentation of nil. If you wish to make a CGImageRef from a RAW image, use CIRAWFilter in the CoreImage framework.
