## Detailed Description

CameraImageProcessing provides control over post-processing done by the camera middleware, including white balance adjustments, contrast, saturation, sharpening, and denoising

It should not be constructed separately, instead the `imageProcessing` property of a Camera should be used.

      Camera {
          id: camera

          imageProcessing {
              whiteBalanceMode: Camera.WhiteBalanceTungsten
              contrast: 0.66
              saturation: -0.5
          }
      }
