Hugin 0.7 is wonderful

I've just followed through the tutorial as mentioned by
http://user.cs.tu-berlin.de/~nowozin/autopano-sift/


which came about when I tried to learn about autopano-sift.


This led to Rob Park's tutorial which is the best for me.
I had difficulty reading it until I discovered the following:

1) the tutorial mentions 3 different software.
autopano-sift GUI version, called autopanog.
Don't confuse this with autopano which comes with hugin.

the output of both autopano and autopano-sift is a .oto file and make sure the path names are stored, as recommended.

2) The input to hugin is the .oto file which also contains the file names that need to be stiched.

3) The output of hugin is after the stiching(done by nona), which is recommended as multipart tiff(a series of files with names*.tif) which still needs to be blended with enblend.

4) enblend needs to be executed from the command line.

There are options for executing it from the hugin GUI but is not recommended by Rob Park.


Extra things with hugin.
With hugin, it is impossilbe not to be able to stich panoramic pictures. We can always manuall place the pictures where we want them.

Use the panorama viewer to select the files that you want to be included and to see their placements.

Disable wrongly placed pictures and insert control points which autopano misses.

The endblend 3 that comes with hugin 0.7 beta 4, does not seem to work. I had to revert to enblend 2.5 which comes with hugin 0.5.

the main problem with autostick is that it keeps on getting out of memory errors which necessitates a redoing of everything. Hopefully with hugin, I need only to redo steps that had failed with options to output at various quality and resolutions, with the added bonus of never failing and ability to use all photos, that can be placed manually. No need to do any pano editing any more.
