# NSImage.DynamicRange.unspecified

Indicates that the dynamic range treatment of the image is unknown or otherwise unspecified.

## Declaration

```swift
case unspecified
```

## Discussion

Discussion The imageDynamicRange property can return this type when the system can’t determine the High Dynamic Range (HDR) of the image. Otherwise, the use of this value isn’t encouraged and results in undefined behavior.
