You tell PTGui how many pictures you shot per row and how many rows are involved in those pics with blue sky for example. The pics are placed in a grid one after the other when you have told the program about the way you shot your pics.
You can download a trial to test the program.
See also www.Kolor.com : AutopanoGiga. Similar program to PTGuiPro. But this is not my personal favorite based on older versions of Autopano. At that time I decided to go for PTGui. But there are different updates of Kolor since then but I did not upgrade all of them. I prefered to have more control about the software instead of a lot of things happening automatically. So I did not test the latest versions. But you should give it a try as well.
Have a look to PTGui's information about "templates". This is a special term used to save data of a pano with minimum CP distance close to 1.0 for example trimmed by adding manual CP = Control Points or deleting bad ones. You can save this data to a "Template", and "Apply Template" stitching your next pano. This helps PTGui to find Control points automatically.
