# 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 scaler that automatically calculates the exposure level for each image it scales. note: Denoiser scaler instances that use auto exposure ignore their exposureTexture property. This property’s default value is false.
