After you do a scale transformation of a Smart Object with an applied Camera Raw filter, the applied Camera Raw edits don't scale with the image. They are still applied, but not in the same area that the edits were applied. For example: I do a Camera Raw edit of a smart layer that is of a face. and use the brush to lighten up the face, and then apply the Camera Raw. I then scale the layer that has the smart object of the person, and the camera raw edit. The scaled version has the Camera Raw edit, but it's no longer isolated to the face.
