It works fantastically.
Looks real good! That is an extremely nice feature in the new version of Lightroom! RAW Panoramas were practically non-existent, you had to go through RAW-to-TIFF adjustments, then open in dedicated Panoramic stitching software, and on and on.
I have manually stitched panoramas before, which is an extremely time consuming project, and if you’re not very careful, you won’t get any better results than the automated software! It is sort of neat though, to manually “put the pieces together”. I might have to download the 30 day trial, and try out that stitcher myself!
