Since 1966 I live in Japan, and since 1969 in Tokyo. I hope you enjoy
life in Japan!
I must have started taking panoramas about the time you came to Japan,
but I still don't have a website to display them. They occupy gigabytes
of hard disk space on different computers.

do the same?

fascinating to see panoramas of Tokyo. Maybe one day we can take some
- Hi John,
Thank you for your comments.
Yes, at the time I did the stitching, my workflow was not very good.
Following your advise, I have remade the panorama and posted it again
at the same place. Most of the stitching errors should be gone.
Let me know if you still see leveling issues.
I took this panorama with a Nikon D70 and Tokina 12-24 (at 12 obviously).

quite as good as it might be. When you have such nice, clear
reflections of features in the water surfaces, which are naturally
vertically aligned, it's easy to get perfect levelling.
Of rather more concern is the bowing of straight line features. See
the low wall and paving lines below the main pyramid. These show
You don't mention how you stitched the images. If using PTGui, see
this levelling tutorial:
Again if using PTGui, the curved straight line features are probably
due to bad lens parameters evaluated by poor optimization.
Calibrating the lens parameters would solve that problem.

as a spherical panorama. I used to shoot ONLY cylindrical panoramas for
years, and ran into this quite a lot. It was confusing until I found
the settings to force the viewer to treat my images as cylindrical. It's
easy enough for the viewer to do this automatically--the give-away is
that the vertical and horizontal pixel counts are not in the raio 2:1.
But not all do...

file produced from a cylindrical input. I had some problems verifying
this as Pano2VR failed to convert the .mov file to equirectangular
properly; the output file was only 1KB! Fortunately, it did manage to
produce a new .mov file which could then be converted to
