# defaultRectForExposurePoint(ofInterest:)

The default rectangle of interest used for a given exposure point of interest.

```
func defaultRectForExposurePoint(ofInterest pointOfInterest: CGPoint) -> CGRect
```

## Parameters

`pointOfInterest`

The point of interest for which you want the default rectangle of interest.

## Discussion

For example, pass `(0.5, 0.5)` to get the exposure rectangle of interest used for the default exposure point of interest at `(0.5, 0.5)`.

This method returns `CGRectNull` if [`isExposureRectOfInterestSupported`](/documentation/AVFoundation/AVCaptureDevice/isExposureRectOfInterestSupported) returns `false`.
