Hi linse, thanks for sharing. Any rough description of the steps you took?
I'm sure you probably know the first step since you've stitched so many panoramas. But just in case ... first of all, for complex scenes where distortion of building architecture is obvious eg "Arles - Inside the Amphitheatre", it is critical to shoot the scene around the optical axis/nodal point of the lens. Using a tripod may not be good enough especially in the portrait orientation. Have a look at the
Panosaurus tripod head or do a Google search on optical axis/optic center/nodal point.
Next I use the freeware Panorama Tools and it's shareware graphical user interface (GUI)
PTGUI to to manually set the control points. There are lots of tutorials on the web on Panorama Tools.
PTAssembler is another popular GUI for Panorama Tools. I also set vertical control points which will automatically correct yaw, roll and level the horizon when Panorama Tools optimised the images. For the really difficult fit like the railings in "Arles - Inside the Amphitheatre", you can use the Morph-to-Fit function.
Once I am happy with the stitched image, it is exported to Photoshop as layers where I can blend away any other artefacts or malalignment. As I mentioned earlier, the steps are tedious but with practice, your stitched panoramas will be seamless.
