This is a handheld pano of around 180 degrees with 17 images to stitch..... originally 3,000 by 6,000 pixels or so.
This is near the end. This new second pass is an improvement, but some improvements are hard to see at this enlargement. I pushed LR camera raw settings too much before. Exposure down, recovery up, fill light etc. Somehow that caused some problems with the panorama stitching. Several small but bad problems. This time the stitching worked great. Don't know why (and don't really care). Then I worked with the masks and moved some lines and the details cleaned up. Just a little clone stamp. I did a 16 by 33 test print, and the only problem was some content aware "debris". I know it is there and if I point it out, it is obvious. A little clone stamp or crop will finish it. Goal is a 36 by 72. Not fine art, but commercially nice.
The color issue were: with color boost the sky became too much. The plants or the right had different color than the ones on the left. The clouds blew out easily, and the dark horizon needed enhancement. Solution: I had to do several adjustments with hand painted masks and work on the blends. Each adjustment was with CM.
