Alfred, I spent a lot of time in Florence for my job. Looking at your picture I'm a little puzzled about the color. Is there so much green? It's a question. About the light unfortunately at the moment of the shot it was not the best. I see a strip from the central "rosone" to the base of the bell tower. This is my opinion, of course.

Stitch quality can be improved, looking at your Taj Mahal picture that is done much better.

For the building an 8
for the stitching an 7
Makes 15/2= 7.5
No 7.5 on the rating scale , OK an 8.

If you look here: http://myolympus.org/document.php?id=3491
you will see that there is a lot of green marble in the facade

Not sure what you mean here. Which strip are you referring to ?

Alfred, the first question is better expressed saying "because I'm missing from Florence since 3 or 4 years and they could have made some maintenance, is the green in the marble real?".
About the strip, the light on the central rose windows (rosone) is higher than thje one in the lower part. In addition the light in the base of bell tower is higher than the one in the higher part of it. Sorry for my English.

You have captured this well Alfred, it is a tall building and not easy to get it all in!
The verticals are not upright are they, or is it my eyes?
The tower seems to be bending in the middle:-)

Dave,

the whole panorama is actually a bit messy as has been pointed out. Despite using the same exposure and RAW conversion settings for all four images, there were huge brightness differences in the sky of the individual images:



Then the perspective was a bit crazy, as I had to be very close to the cathedral. See the intermediate result of PTGUI:



In post-processing I had to make the top part of the church brighter, so that the associated sky would be brighter too, to make the transitions less harsh.

Then I had to apply a blurring technique to smoothen the brightness transition in the sky. In any case I have other night panorama sequences of that church. I hope that the stitches will come out better this time.

Alfred , "including pictures in a comment" is a great improvement to the website.

Thanks very much...
