# kCMFormatDescriptionCameraCalibration_LensRole

## Declaration

```swift
let kCMFormatDescriptionCameraCalibration_LensRole: CFString
```

## Discussion

Discussion Specifies the particular use of the lens in the camera system (e.g., left or right for a stereo system). For a stereoscopic camera system, one lens should have the left role and another should have the right role.
