AutoStitch
I realize that you get what you pay for, and the price of AutoStitch
(free) was certainly right. I did a 180 degree pan of my back yard in 7 shots. Each shot individually was sharp, the stitching process was flawless, but the resulting picture was somewhat fuzzy. Does anyone know of a solution for this problem using the available options, or is fuzzy as good as it gets with this software? If the latter, can someone suggest a reasonably priced alternative. The photo's were taken with a Fuji E550 at 3 megapixels in auto mode. I've only seen any fuzziness out of Autostitch on a couple of shots, and each time it's been when there was no way to resolve differences between shots - in one, a tree had been moved by the wind, in another, a dog had lifted her head. There are some parameters you can play with (which are briefly discussed in the readme file that came with it), but differences of that nature just aren't resolvable. The shorter the focal length (and hence, wider the angle) of your shot, the more distortion you introduce around the edges - and the more difficult it will be for Autostitch to do a good job. More shots at a slightly longer focal length may help. I got up on my roof with a tripod and made a 180-degree panorama of my neighborhood, but I took something like 27 pictures to do it (roughly a 3x9 grid). The resultant image - AFTER CROPPING - was around 150 megapixels. It took a while to process, but there's a ton of detail, and when resized to a more reasonable level for printing, any aberrations from the stitching process will be much less visible. steve |

"There's a freeware version of The Panorama Factory that has none of
these problems." With Panorama Factory you can get mostly pretty good results but With Hugin (equipped with Panotools and Autopano) you can get even much better results. http://hugin.sourceforge.net/ Markku Virtanen |

One thing You could try is to decrease the feather width even to zero.
Please read more he http://enblend.sourceforge.net/ Markku Virtanen |

I tried the zero feather width but it doesn't seem to make a noticable difference in hiding the seams; especially in the sky. I replaced the first pano with the zero feather version at the same URL: http://www.justus.ca/misc/panoramas.htm Any other suggestions? Paul's post suggested that I try Enblend but I thought that was automatic, as I've explained in the reply to his post. |

Here You can find somewhat more information about using Enblend with
Hugin: http://rbpark.ath.cx/articles/create.html Markku Virtanen |

I did get Enblend to stitch the panorama by following the "One Guy With Camera" instructions that you recommended. Enblend does do an excellent job of blending but I still have one problem. When I try to output the multiple Tiff files using Hugin, the files are created OK but immediately after the final file is processed by Hugin they all get automatically deleted. The only way that I could get the files for Enblend to process was by copying the files to a separate directory, one by one as they were completed by Hugin. I still could not get the last file because it gets deleted immediately after processing and there's no time to copy it. I also tried selecting the "Tiff" output with the Soft Blending option from within Hugin but Enblend crashes during the processing with an error message saying that Hugin gave it only a single file to process. Do you have any ideas on how to avoid this problem with the files getting automatically deleted? I guess Hugin is doing the deleting because Enblend is not even running at that point. |

I think there is a bug somewhere cocerning this procedure. I just tried
the same thing and it happened just like You said: the tif -files are deleted right after they are made ready. But when I used PTStitcher instead of nona engine everything went fine. Markku Virtanen |

I just happened to stumble across the answer. The "Delete remapped tiff files" check box on the Enblend tab of the Hugin Prefences menu item has to be unchecked. Doing so stopped the automatic deletion problem. Thanks for your help. I just select tif output and end up with a final file that does not need to be joined.

An example (low res) is at www.paulbech.id.au/photos/museum.jpg I made first 'Multiple TIFF' files with PTStitcher (with 'exposure correction' and with 'feather width' value zero) from five jpg -pics. Then I opened those five tif -files to a new project and used nona with 'Soft Blending' to get one panorama picture (tif -file). Here you can see the result: http://members.tiscali.fi/markkvi/Panorama/Page.html At least there are no visible seams in the sky nor anywhere else. I admit that the sky is not very good at all but that is mostly caused by quite heavy JPEG -compressing. Markku Virtanen |
