I have been very pleasantly surprised recently, at just how well the Merge to Panorama feature is working in Lightroom. The image you see above is three vertical shots taken on the Olympus EM5 at 12mm. When I first tried the stitch I used Photoshop, which made a complete mess. This version though was done in Lightroom using the Cylindrical panarama blening option. Look at the boat mast and rigging. The software has done a great job.
I shot the image almost 2 years back but had largely ignored it due to the stitching problems. I think I might revisit some of my other images now.
Have a great weekend everyone.
