As I'm getting into the world of panorama's, I'm trying out different software to find out what suits me best. Here are the results so far. Maybe someone else can benefit from my tests.
NOTE: All duplicate panorama's you see here only differ by one factor; the program used to stitch them together. All images have undergone the same treatment in Photoshop CS3 and has been saved as TIFF files before stitching. Hence, the variety in the results seen here are solely dependent on the capability of the software used in each case.
