I'm currently traveling through South America on a round-the-world trip. In addition to my photography I’ll be sharing my experiences (the interesting ones anyway) on my website.
In my portfolio you'll find images from over 40 different countries with new images being added regularly.
I hear very good things about Gimp... its been on my to-do list to try out for quite a while.
Pandora and Autopano also use Panotools core which Hugin, and a lot of other open-source panorama software applications use.
Thanks for all the comments... I always find it useful to see how other people do the same things I do - quite often I actually learn a lot that way. posted in How to Create Panoramas good enough for Dreamstime
