Labuda posted a great panorama of Krakow this morning. After seeing his shot, I tried to make my own. I live on a cul-de-sac. I put my camera in the middle of the street and then started taking shots. I'd move the camera 10-15 degrees each time. Any ways, when I brought my pictures into Photoshop and started laying them out, I noticed that there was noticeable distortion at the far ends of each picture...all of the shots curved downward...just enough to make the ends of the picture not line up right. So the panorama turned out to be garbage because of that. I was shooting with a 28mm lens (I guess 44mm on the 20D). What DO you have to do to make a good panorama? How do you avoid curvature (or do I just have a bad lens!)?

Some lenses have more distortion than others, but that's not the real issue here. Without "warping" the pics, you cannot get perfect alignment. The wider lens you use, the worse this becomes. Pano software compensates for this by warping the originals to make ends match, using control points that are either set automatically or manually. Labuda used what is arguably the most capable pano stitching system available, the PTGUI front end and PanoTools stitching engine. PanoTools is free, PTGUI is not free but is inexpensive. This combination, although powerful, is not the easiest package to use. There are other decent packages out there (Panorama Factory is one that is consitently rated well) that might be somewhat more expensive but are easier to use.
