It is "bokeh panorama" or so called Brenizer method. Google for that, if you don't know abaut it.
I made 40 shots with 200 mm at f/2.8. Subject was covered with 4-5 shots in landscape composition. Other shots were made around the subject. That final image is cropped a lot, because some of the shots were not overlapping, thus, when I make a panorama, the output was in 2 separate images.
Thanks. I had heard of the Brenizer Method before, but hadn't bothered to look it up until now.
Thanks for the nudge
