Just for grins I found a two frame pano I did awhile back of the Chicago skyline from the museum campus.
The longer thinner image is cropped to max after pano merge in LR.
The larger image is the same two frames merged and then the warp slider pulled all the way to 100.
As one would expect the warp tends to elongate the image bottom to top while keeping the same relative dimension left to right.
Same processing applied to both via LR.
