Default Accidental panorama

http://www.flickr.com/photos/monza76...n/photostream/

Hope this link works. An accidental panorama. Excuse the image quality issues (especially exposure). This was not shot as a panorama so the camera was on program and changed exposure values as I turned. It wasn't until nearly a month later that I realized I had enough frames to stitch together. This is the part of the town I live in. The full sized image is 30000 pixels wide.

Hm,
a tad small to really "pixel-peep"

As for the different exposures - why not give autostitch a try? (Link: http://cvlab.epfl.ch/~brown/autostitch/autostitch.html) It has an exposure blending algorithm, which might come in handy here.

Hint: in the options, set size to 10% or 25% as long as you don't let the program render the final panorama. Much faster, you can adjust settings and then be sure it works.

I like those "accidental panoramas" - it's like an unexpected present of some kind.

Regards,
Th.

it looks like a pretty good panorama
the computer at work would nt show it very big
i use autostitch too and find it works really well most of the time
even blending sky tones that are not exactly the same

thkn what do you mnan by "Hint: in the options, set size to 10% or 25% as long as you don't let the program render the final panorama. "

You can choose how big autostitch will render the panorama. It's in the upper left corner of the options dialog ("output size"). Especially with "accidental panoramas" I often set it to 10% or 25% and disable all rendering options. You'll see how the program alignes thes images that way and it's much quicker than rendering the whole 10.000px+ pano .

I'll swap in and out images and then I tweak the matching options and re-render the small version, sometimes rotating images ("image rotation", right side) is helpful, too. If I am satisfied with my selection of images and the said settings I tune the rendering settings.

If everything looks good I set output size to 100% and quality to 100% (sometimes 99% if 100% fails).

Does that make sense to you?

Regards,
Th.

I don't know if this will work but here is the reference to the 10000pixel wide version.

Pretty neat for an accident.
