Just as I said, I was not able to find better place this month. But I've at least managed to get rid of blurry shots and get geometry right. So, final version is made from three images only; two small gaps were filled with gimp resynthesizer plugin on full auto, try to spot them
Photos taken with N9, by Nokia Panorama, but stitched in hugin,
WTF is the HFOV of N900? Why would I need to care about such things anyway? Frustrating...
I just entered 1 as focal length multiplier. My N9 wrote 28mm focal length to exif; it's obviously not real f.l., but equivalent one, so I decided that multiplier is already here. Seems to work. ~60° HFOV looks resonable for phone camera.
Another uses of hugin are lens distortion correction and creating HDR images from brackets (HDR, not tone mapping. At least I haven't found TM yet).
