Some years ago, the University of British Columbia released a demo version of their advanced software photo stitching process. It is essentially all automatic, but you can tweak quality and size etc. You can also use an almost unlimited number of images so that you can stitch together huge wide angle images from a dozen or so smaller shots.
I use Autostitch for all my panoramas purely because it is simple to use and is one of the best stitching program/apps around. Even Industrial Light and Magic have used the software. Oh, and the demo is free and fully functional.
‘The human visual system has a field of view of around 135 x 200 degrees, but a typical camera has a field of view of only 35 x 50 degrees. Panoramic image mosaicing works by taking lots of pictures from an ordinary camera, and stitching them together to form a composite image with a much larger field of view.
AutoStitch takes a step forward in panoramic image stitching by automatically recognising matching images. This allows entire panoramas to be constructed with no user input whatsoever. AutoStitch is incredibly simple to use! Just select a set of photos, and AutoStitch does the rest: digital photos in, panoramas out.‘
The following panoramas have been stitched using two, three or four individual images. See if you can see the joins. As always, click on an image to get the full size view
