Let's launch PtGui (This tutorial is for version 3.7beta1 and above).

Add some picture in the project. When opened, PtGui adjust the lens to match EXIF data (if they are available).

EXIF popup

Download autopano and unzip the package in some folder.

In PtGui, go to the options menu :

You should put in the autopano directory the path where you unzipped autopano.
The command line argument can be used to improve the result. Leave it blank for standard use.

Launch autopano by Menu : Plugins, Autopano. A new command window is displayed. When it closes itself, PtGui should show you that :

It's the confirmation that autopano has found control points. Just click OK.

You can go to the control point tab to see the newly added control points :

Go the Optimizer tab, switch to simple mode, set your anchor picture and make sure you will not optimize the field of view. Put the Minimize lens distortion to no or Medium.

Optimize.

 

With the panorama editor (CTRL+E), set the horizontal line, center the panorama, adjust projection (cylindrical, spheric or planar).

Reoptimize by correcting lens distortion and it's should be almost perfect.

First, you have to download enblend : http://www-cad.eecs.berkeley.edu/~mihal/enblend. Unzip the software in a folder and setup PtGui to look for enblend in the folder where you put it.

Then you have to activate enblend : it's on the plugins menu, check the enable enblend.

Go back to the Panorama Settings, and choose TIFF output (to work with enblend).

Then go the Create Panorama tab, hit "Set optimum size", choose a file name for panorama and hit "Create Panorama". It's done !
