# AppleLog Sampler

This is sample app for capture with `.appleLog` color mode.

## How

1. Set `automaticallyConfiguresCaptureDeviceForWideColor` of AVCaptureSession to `false` (this might be the most important part)

2. Search for a format in `formats` of `AVCaptureDevice` that contains `.appleLog` in `supportedColorSpaces` and set it as `activeFormat`

3. Set `activeColorSpace = .appleLog` on `AVCaptureDevice`

```swift

private func isAppleLogAvailable(for device: AVCaptureDevice) -> Bool {

    device.formats.first(where: {

        $0.supportedColorSpaces.contains(.appleLog)

    }) != nil

}

private func configureAppleLogIfNeeded(for device: AVCaptureDevice) throws {

    guard isAppleLogAvailable(for: device) else {

        return

    }

    try device.lockForConfiguration()

    defer {

        device.unlockForConfiguration()

    }

    /// set up for .appleLog

    if let format = device.formats.first(where: {

        $0.supportedColorSpaces.contains(.appleLog)

    }) {

        device.activeFormat = format

        device.activeColorSpace = .appleLog

    }

}

```
