# depthOfField()

Simulates a depth of field effect.

## Declaration

```swift
class func depthOfField() -> any CIFilter & CIDepthOfField
```

## Return Value

Return Value The modified image.

## Discussion

Discussion This method applies the depth of field filter to an image. The effect simulates changing the focus of the camera before taking a photograph. The depth of field filter uses the following properties: The following code creates a filter that results in the center cilantro being in focus while gradually blurring to the top and bottom of the image: func depthOfField(inputImage: CIImage) -> CIImage {     let depthOfFieldFilter = CIFilter.depthOfField()     depthOfFieldFilter.inputImage = inputImage     depthOfFieldFilter.radius = 5     depthOfFieldFilter.point0 = CGPoint(x: 2349, y: 846)     depthOfFieldFilter.point1 = CGPoint(x: 571, y: 3121)     depthOfFieldFilter.unsharpMaskRadius = 7     depthOfFieldFilter.unsharpMaskIntensity = 10     return depthOfFieldFilter.outputImage! }
