AVCaptureColorSpace.appleLog2
The Apple Log 2 Color space, which uses Apple Gamut as the color primaries, and an Apple defined Log curve as a transfer function. When you set this as the active color space on an Avcapturedevice, any Avcapturephotooutput or Avcapturestillimageoutput connected to the same Avcapturedevice is made inactive (its Isactive property returns false).
