I have a similar shot of a suspension bridge, hand held, horizontal stitched. I did not go vertical for some reason that day.
Nothing I had would stitch the bridge and get the wires right, CC, ptgui, autopano, etc. I tried LR and was very surprised it got it right.
I believe some of the advantage is that you can stitch a raw file.
Early in January, I did a 2 part horizontal stitch with my Nikon D810, and 20mm 1.8. 2 stitches. No nodal all hand held. Sure I know I broke all the rules. But the light was fading fast.
There was a line of clouds that paralleled the horizon and no matter what I did, none of the software would stitch the clouds. They all got the horizon, but could not wrap the clouds. This was using a LR tiff. I went back and imported the tif files and tried to use LR for the stitch. Same problem.
Then I went back to the raw files, that had been worked up in LR, and exported and tried to make the stitch. It worked perfectly. The only issue is that all the local adjustments were dropped and the files were converted back to raw/dng with no adjustments.
So I learned 2 things.
1. LR and stitching raw files may get around some of problems other tools can't
2. stitch the files first, create the dng, then work on them with local adjustments as all the previous adjustments will be stripped during the
pano creation. Or so it seems.
Very impressive.
