[hugin-ptx] Re: Hugin stacks pictures to one stack, not 360 degrees as I want
Thanks JohnPW from you reply :) But I have already solved the issue (forgot to mention it in the groups, damn the memory of a man). Issue was in the control points, they somehow connected ALL the photos to one and result was one picture. Removing those extra control points and zeroing values from images gave me a good panorama :) Thanks for your help (yet late to notice it :)) -- -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.

How do the control points look? Look in the quick preview window and check show control points. It's hard to know what's happening without more information. You should probably post the PTO file.

Only to those, that have large room or space to stitch up. Getting smaller (more detail-rich) panoramas is kinda child's play but I cannot stitch big rooms together at all. Here is one example: http://filesmelt.com/dl/panorama4.jpg This panorama is made out of 6 pictures. Four that circle the room, floor and ceiling pictures. Room itself is shaped as half-circle. Problems come with floor and ceiling pictures. Here is one that I made with 4 pictures, leaving ceiling and floor pictures away: http://filesmelt.com/dl/panorama12.jpg It looks nice, but there is huge blank spaces at ceiling and floor when we try to make it a ball for viewing. So the panorama is cylindrical. What to do to fix this problem? -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.

[hugin-ptx] Re: Hugin 'Stacks'
I do HDR panoramas, too; but my workflow is completely different: At the field, I always use a tripod, so the different exposures from each camera position all match perfectly. Later when dealing with the files, I create one panorama for each exposure, and then merge them into a HDR; these are the steps I follow: First, I copy all the files from the first exposure to file1, file2, file3... . Then I create a LDR panorama with Hugin, and call it pano1. Without closing Hugin, I copy all the files from the second exposure over file1, file2, file3..., execute the same panorama and save it as pano2. With this technique, I obtain a stack of panoramas pano1, pano2, pano3, ... perfectly aligned, that I can handle with enfuse / pfstools normaly. There is a longer description here: http://edu-perez.blogspot.com/2008/12/panoramica-nocturna-de-barcelona-en-hdr.html, but I am afraid it is written in Spanish. Hope this helps, Edu.

[hugin-ptx] Re: Hugin 'Stacks'
I've used with success the technique described on the tutorial. Let's say you take 3 exposures (well exposed, under exposed, over exposed) of each scene and you capture in total 2 scenes (a and b) to merge in an HDR panarama; you need to set control points in this way: - between the 3 different exposures of a scene; - between the 3 different exposures of b scene; - between 1 shot of a scene and 1 shot of b scene (I prefer to use the well exposed shots for this step because generally you could spot more control points) I hope I've make it clear!

[hugin-ptx] Re: Hugin 'Stacks'
there are many different ways that lead to Rome... or to Barcelona in your case, Eduardo. stitching and stacking or stacking and stitching are the two families. http://panospace.wordpress.com/2008/10/08/exposures-stacks/ since most tools can't handle yet the 360° seam nor zenith/nadir for full sphericals I use stacking first. It has also the bonus of being faster. For true HDR it does not really matter because the stitched result must be tonemapped and the tonemapping tools don't handle the seams...
