# isGeometricDistortionCorrectionSupported

A Boolean value that indicates whether this device supports geometric distortion correction.

## Declaration

```swift
var isGeometricDistortionCorrectionSupported: Bool { get }
```

## Discussion

Discussion Some devices benefit from geometric distortion correction (GDC), such as devices with a very wide field of view. GDC lessens the fisheye effect at the outer edge of the frame at the cost of losing a small amount of the horizontal field of view. When you enable GDC, the device upscales the corrected image to the original image size.
