# IKFilterBrowserDefaultInputImage

The key for the default input image.

```
let IKFilterBrowserDefaultInputImage: String
```

## Discussion

The associated value is the <doc://com.apple.documentation/documentation/CoreImage/CIImage> object to use as the default input image for the filter preview. Setting the image to `nil` causes Image Kit to use the image supplied by the framework. You can also set the input image and other parameters during the notification [`IKFilterBrowserWillPreviewFilterNotification`](/documentation/Quartz/IKFilterBrowserWillPreviewFilterNotification).
