```

## Return Value

The modified image.

## Discussion

This method applies a preconfigured set of effects that imitate vintage photography film and emphasize warm colors.

The photo effect transfer filter uses the following property:

- `inputImage`: An image with the type [`CIImage`](/documentation/CoreImage/CIImage).

The following code creates a filter that adds brightness to the input image:

```swift
func photoEffectTransfer(inputImage: CIImage ) -> CIImage {
    let photoEffect = CIFilter.photoEffectTransfer()
    photoEffect.inputImage = inputImage
    return photoEffect.outputImage!
}
```

In the photo on the right, a photo effect transfer filter is applied, transforming the colors in the image to a higher contrast.](images/com.apple.coreimage/media-3545015@2x.png)
