Terribile results, unnatural panoramas, artificial-digital, blue shocking everywhere, hyper contrasted, wrong hue and an ultra saturated sky and blue (!) dark clouds... this I can frankly wrote after having done these works for 25+ years and using only PTGui as stitcher, to begin to do the panorama-puzzle, always using AEB mode, 3 or more shots for each frame.Here's one example made with P4P images: Virtual Tours Made Simple
With the sun and luminous clouds even 10+ AEB shots if needed.
I see also the typical gosts of the terrain due to different luminosity between adiacent frames (with moving clouds).
Ha!
