YES, I like this function – and also use it to ‘undistort’ pics from our grandson, when taken with a mobile’s wide angle lens.
I didn’t know this function. I’ve a 15-30mm lens I use sometime. It works ok that function.
However I had to use horizontal/vertical, the diagonal results in other distortions.
My wife has often asked me to help fix wide angle group shots taken at her hospital where people on the extreme left and right are made to look deformed and grotesquely fat. The Volume deformation feature of Viewpoint is great for addressing that problem. I’ve been using it for years.
