Search TipsLens Distortion
The Lens Distortion node uses a simple Brown-Conrady distortion model, like OpenCV. Nuke uses a number of more complex models for its Lens Distortion node, but the Nuke Stage values can still be translated to the Nuke node.

| Enabled | Enabled | ticked | If unchecked, this node will be omitted from the compiled image processing graph. Any incoming connections will be forwarded to the first output port, if any. |

| Override upstream CameraRef params | OverrideUpstreamCameraRefParams | ticked | If enabled, this mode will use the locally set parameters, regardless of any valid upstream CameraReference nodes. Otherwise, parameters will be taken from a valid upstream CameraReference node. |
| k1 | K1 | 0.00000 | First radial distortion harmonic in millimeters. The distortion parameters can be used in Nuke Stage by adding a Lens Distortion node with a camera override. |
| k2 | K2 | 0.00000 | Second radial distortion harmonic in millimeters. The distortion parameters can be used in Nuke Stage by adding a Lens Distortion node with a camera override. |
| Distortion Centre | Centre | 0.000, 0.000 | Position of the distortion center in millimeters, from -1 to 1 with 0 as center of image. The distortion parameters can be used in Nuke Stage by adding a Lens Distortion node with a camera override. |
| Sensor dimensions | SensorDims | 36.000, 20.250 | Size of the camera sensor, in millimeters. |
| Black outside | BlackOutside | ticked | IF enabled, black pixels will be rendered where there is no content to replace it. |
