/* TODO: OpenEXR 3.2 metadata
*
* New Optional Standard Attributes:
* - Support automated editorial workflow:
* reelName, imageCounter, ascFramingDecisionList
*
* - Support forensics (“which other shots used that camera and lens before the camera firmware was updated?”):
* cameraMake, cameraModel, cameraSerialNumber, cameraFirmware, cameraUuid, cameraLabel, lensMake, lensModel,
* lensSerialNumber, lensFirmware, cameraColorBalance
*
* -Support pickup shots (reproduce critical camera settings):
* shutterAngle, cameraCCTSetting, cameraTintSetting
*
* - Support metadata-driven match move:
* sensorCenterOffset, sensorOverallDimensions, sensorPhotositePitch, sensorAcquisitionRectanglenominalFocalLength,
* effectiveFocalLength, pinholeFocalLength, entrancePupilOffset, tStop(complementing existing 'aperture')
