J-P,
I like your pano, but I think you should change the focal point. I would swing it 180 degrees so the initial view is of the podium instead of the splotch on the wall, is that lens flair? I always have a hard time getting rid of that myself in Photoshop as I'm a newbie too - but you could improve it a little by just changing the initial view/starting point.

J-P,
I like it too. If you hAdn't said, I would have thought it an English village church. Very sombre.
But that's not why I'm writing. While the pano is rotating the resolution is low - that's normal, I suppose - but when I stop the motion, resolution only improves if I keep my finger on the lefthand mouse button. If I lift my finger, the image remains motionless, but resolution returns to what I think is the motion setting. I don't know enough about ImmerVision to offer a cure.

Focus, in anycase, seems a bit 'soft'. Any idea why?
Mark

It's a nice panorama and I'm sure it looks a lot sharper in the original full size version. The Gallery panoramas are limited to a maximum of 3000x1500, I believe, which isn't big enough for high quality full screen presentation, and there may be excessive compression applied too.
There are a few very small imperfections in the stitching and the nadir is untidy, with the camera and top of the tripod visible. Better patching is possible given the nature of the floor. But overall it is is quite good. What software was used to stitch the panorama?

Hi ! You're right about the starting viewing point ! I'd like to move it, but i just don't know how !?!
I used Stitcher Express to stitch the images and Pano2QTVR to create the spherical result...
Any tips on how to change the focal point ?
TIA,
J-P.

Hi Mark !
It is indeed very dark ! ...in fact, it's darker in reality than on the image !
I guess the quality is not as "clean" as it could be because:
1) i don't know well enough how to manage the sizes, be it from the stitching to the *.MOV file
2) i had to shoot at ISO 800, and the D200 is NOT the best camera for high ISO shooting
3)i don't know yet what the best way to sharpen images that are going to be "treated" for spherical panorama (i applied the same sharening technique that i use for my "normal" photography) !
Of course, any tips is more than welcomed !
Cheers,
J-P.

Hi John !
You're right about the Nadir: i have to find the correct way to shoot it so that i can clone out the tripod+feet plus their shadows !
I had to buy and use Stitcher Express, after having tried Hugin, PTGui and PTAssembler, wich ALL were unable to give proper results !
Cheers,
J-P.

I'm sure Hugin, PTGui and PTAssembler were ALL equally capable of giving proper results. It's just that an inexperienced user like yourself would not be able to get the best possible results.
You can edit the nadir region of your existing equirectangular image by extracting a rectilinear view using a variety of techniques - usually with pano2qtvr or PTEditor. See the PanoTools Wiki for more details at tinyurl.com/2t4qep .
