This will change with the upcoming React Native Re-Architecture, so that instead of writing a temporary file which you have to read again, this function will immediately return an Image HostObject on which you can directly interop with the underlying `UIImage`/`Bitmap` for faster image capture.

### Taking Snapshots

Compared to iOS, Cameras on Android tend to be slower in image capture. If you care about speed, you can use the Camera's [`takeSnapshot(...)`](api/classes/camera.camera-1#takesnapshot) function (Android only) which simply takes a snapshot of the Camera View instead of actually taking a photo through the Camera lens.

Due to limitations of the React Native Bridge, this function can not be awaited. This means, any errors thrown while trying to start the recording (e.g. `capture/recording-in-progress`) can only be caught synchronously (`isBlockingSynchronousMethod`). This will change with the upcoming React Native Re-Architecture.

## Focussing

```ts

await camera.current.focus({ x: tapEvent.x, y: tapEvent.y })
|
|
|
|
|
```
|

The focus function expects a [`Point`](api/interfaces/point.point-1) parameter which represents the location relative to the Camera View where you want to focus the Camera to. If you use react-native-gesture-handler, this will consist of the [`x`](https://docs.swmansion.com/react-native-gesture-handler/docs/api/gesture-handlers/tap-gh#x) and [`y`](https://docs.swmansion.com/react-native-gesture-handler/docs/api/gesture-handlers/tap-gh#y) properties of the tap event payload.

So for example, `{ x: 0, y: 0 }` will focus to the upper left corner, while `{ x: CAM_WIDTH, y: CAM_HEIGHT }` will focus to the bottom right corner.
