Limitations on file sizes that can be stitched due to Windows 98 limitations. Not sure if this holds true on the Macs. 2. The waves would be starting and stopping in all different places. The inability for software to properly assess the scene and excessive warpage caused by lenses. Many stitched images do not accurately reflect what was in the scene.
Movement is a big issue with stitched shots.
For example, if a tree is moving ever so lightly in a breeze this can be captured without blur with a given shutter speed. However, when you take two shots, the tree would need to be in exactly the same area for each shot for the stitching software to fully acknowledge what and where it should stitch. No matter how sophisticated the software becomes, it can only produce output as good as the film you offer it. Another problem like this is a busy street scene. It's almost impossible to capture with multi-shot stitched pans unless no cars or people were moving between shots.
