# exposureAdjust()

Adjusts an image’s exposure.

## Declaration

```swift
class func exposureAdjust() -> any CIFilter & CIExposureAdjust
```

## Return Value

Return Value The modified image.

## Discussion

Discussion This method applies the exposure-adjust filter to an image. The effect uses multiplication of color values to simulate the change of exposure within the photo. The exposure-adjust filter uses the following properties: The following code creates a filter that adds brightness to the input image: func exposureAdjust(inputImage: CIImage) -> CIImage {     let exposureAdjustFilter = CIFilter.exposureAdjust()     exposureAdjustFilter.inputImage = inputImage     exposureAdjustFilter.ev = 2     return exposureAdjustFilter.outputImage! }
