As I've indicated in the past, making panoramas from aerial photos is very difficult. Even if a long straight or a slow turn is planned and well-executed in the airplane, I often see severe alignment problems in post-processing, or, the creation of unreal landscape landmarks as the software tries to stitch photos taken from different locations. Sometimes I can manually fix them, sometimes I cannot. My success rate is about 40-50%.
I was able to create just a few panoramas from my Purcell Mountains flight. Below are the ones that I like the best. The panoramas are mixed in with all the photos in the Purcell Mountains - British Columbia gallery.
I hope that you like them.
