For you Windows users, there is a free photo stitching program available on the
AutoStitch website that is extremely easy to use. Maybe not professional quality but works great for the average shooter.
The Program:
Once the options are set, you just open the program and then open the files...that's it. It will produce an image called "pano.jpg" (if the file already exists from a previous stitching, it will be overwritten!).
Taking pics:
-make sure there is ~30% of overlap between the pics
-turn the camera when taking the pics, not your body
The Setup:
-instead of explaining it, this is what I have...

-You may want to mess with the 'output size'.
