# isHighResolutionStillImageOutputEnabled

A Boolean value that indicates whether the receiver should emit still images at the highest resolution supported by its source `AVCaptureDevice` objects `activeFormat` property.

```
var isHighResolutionStillImageOutputEnabled: Bool { get set }
```

## Discussion

By default, `AVCaptureStillImageOutput` emits images with the same dimensions as its source [`AVCaptureDevice`](/documentation/AVFoundation/AVCaptureDevice) instance’s `activeFormat.formatDescription`.  However, if you set this property to <doc://com.apple.documentation/documentation/Swift/true>, the receiver emits still images at the capture device’s [`highResolutionStillImageDimensions`](/documentation/AVFoundation/AVCaptureDevice/Format/highResolutionStillImageDimensions) value.

> Note:
> If you enable video stabilization by setting `preferredVideoStabilizationMode` to <doc://com.apple.documentation/documentation/Swift/true> for any output, the high resolution still images emitted by `AVCaptureStillImageOutput` may be smaller by 10% or more.
