A key for progressive chromatic noise tracking (based on ISO and exposure time).

## Declaration

```swift

```

## Discussion

Discussion The associated value must be an NSNumber object that specifies a BOOL value (true or false). The default is true. This option has no effect if the image used for initialization is not RAW.
