I don’t remember distortion having more than one value in versions of Image Modeler before version 2009. I am happy to see this, I thought the distortion model was too simple in earlier versions. Where can I find more info on the new distortion model Disto 3 5 (-3i 5i)— ? The docs are pretty bare in this regard. Does it support fisheye distortion now?

Anyone able to shed some light on this please?
