I'd love to tell you that this was a carefully planned and executed image, made with lots of loving aforethought.
The reality is that when I was reviewing the images in Bridge I noticed that I had taken two shots from opposite sides of a wall (though not, I think, at the same elevation), though the right one was taken before the left.
Although clearly not a true pano, I thought that they would stitch together pretty nicely into a dual point of view.
Actually I still do. Your mileage may vary.
