# bloom()

Adjusts an image’s colors by applying a blur effect.

## Declaration

```swift
class func bloom() -> any CIFilter & CIBloom
```

## Return Value

Return Value The modified image.

## Discussion

Discussion This method applies the bloom filter to an image. The effect softens edges and adds a slight blur effect. The bloom filter uses the following properties: The following code creates a filter that results in a hazy effect on the image: func bloom(inputImage: CIImage) -> CIImage {     let bloomFilter = CIFilter.bloom()     bloomFilter.inputImage = inputImage     bloomFilter.radius = 10     bloomFilter.intensity = 1     return bloomFilter.outputImage! }
