# isAutoExposureEnabled

A Boolean value that indicates whether MetalFX calculates the exposure for each frame.

## Declaration

```swift
var isAutoExposureEnabled: Bool { get set }
```

## Discussion

Discussion Set this property to true to create a temporal scaler that automatically calculates the exposure level for each image it scales. note: Temporal scaler instances that use auto exposure ignore its MTLFXTemporalScaler/exposureTexture property.
