Thanks for this and it is educational. You have it turned on by default, but there are two methods, right? So which method does default activate? Thanks.

I've set it for horizontal distortion to be applied by default, as that keeps straight lines straight and doesn't crop. That's good for shots that include buildings, so it seems like the better general-purpose solution.

It only takes one click to switch to diagonal correction, which does a better job with people near the corners, but at the expense of bending straight lines and cropping the (now curved) edges.  You can also experiment with the extent of the correction by moving the slider.

Note that either of these corrections changes the aspect ratio of the shot, making it narrower. You may then choose to crop it to the original aspect ratio, which takes out some of the sky and foreground, which is actually a very good idea if you've taken a UWA shot with the camera held horizontal, as you've probably picked up more foreground than you want in the composition.
