# AVCaptureDevice.WhiteBalanceGains

A structure that defines RGB white balance gain values.

## Declaration

```swift
struct WhiteBalanceGains
```

## Topics

### Creating white balance gains

- [init()](avfoundation/avcapturedevice/whitebalancegains/init().md)
- [init(redGain:greenGain:blueGain:)](avfoundation/avcapturedevice/whitebalancegains/init(redgain:greengain:bluegain:).md)

### Isolating gain by color channel

- [blueGain](avfoundation/avcapturedevice/whitebalancegains/bluegain.md)
- [greenGain](avfoundation/avcapturedevice/whitebalancegains/greengain.md)
