Is it possible to improve this pano somehow or it's ok?

I just took these photos a few minutes ago and Autpano did an excellent job, it wasn't even necessary to edit anything manually, it just worked...

However, I'm not an expert on Autpano, I'm just trying it out and I might have missed a couple of videos. But I did watch some of the tutorials already.

First, what I want to know in a general way is if there's anyway to improve this pano somehow?

Second, is there anyway to reduce that fish-eye effect and make it more planar? I tried several projections, spherical seemed the best one. Any other way to make it more planar or not possible?

Here's a low res version of the photos I took:

And attached is the final result...

Try Panini
http://sourceforge.net/projects/pvqt/

ps. where was that shot? Looks like an interesting place.

I haven't tried it yet, just looked at the website you posted and Panini's description says:
Panini is a visual tool for creating perspective views from panoramic and wide angle photographs. More than a pano viewer, more than a view camera, with features of both. For Linux/Unix, Win32, and Mac systems with OpenGL 2.0

Is this just a pano viewer or does it allow me to "fix" prespective problems and save the "fixed" picture? What I really wanted was to "fix" the picture and save it, not use a pano viewer to view the photo...

This is in Algarve, Portugal (where I'm from), this is where I am (on vacation) exactly:

Panini is a viewer where you can switch projection mode, adjust some viewing parameters and save the corresponding image(s)...

Here is a version of your pano where I used Panini (the software) to switch to from spherical projection to Panini projection and then used Eye near (Ctrl + right) to adjust the result.

BTW - especially when using a GPU version - you can change the FOV, move the center point and test the different projection modes without leaving Autopano...

The reason you want to "fix" you pano but can't is explained there: http://slash72.club.fr/gurl/MODES-PROJECTION/en_prefecture_rectiligne.htm

What if I can't use the GPU? My laptop is kinda old...

You can do it, but it's much slower...

Well, I want to try similar results to those to see how I like it... Do I just need to set it Planar and change the center point like in your examples above, correct?

- 1rst step: level the panorama accuratly using the Verticals tool (you need that because you don't use a tripod and a spirit level)
- 2d step: select the best center point location, moving it to the right or the left but leaving it on the very same horizontal line (that is the horizon - see step 1)
- 3rd step: use the crop tool to crop out the far left and far right portions of the pano so that the horizontal FOV is 90° or less.

Nice to see another portuguese user of Autopano!

There are quite a few, they probably are not registered here though :P
