Here is my very first gizmo that I ever put out for the Nuke community. I started out after a series of classes I did with Victor Pérez (which I'm thankful for encourage me to publish this) and I finally got it to work. It split the channels for transform manipulation, allowing to create subtle effects that could mimic some of the RGB distorsion you get from some lenses. You can activate a mask to isolate the effect in a desired area of the image.
