Hi all
Here's some panoramas made using Autopano Pro, easily the best panorama maker I've found.
I fed it the 47meg TIFF's, and it produced 130meg PSD files for photoshop

perfectly blended, all that was needed was to crop the edges.
Some of the shots are horizontal panoramas, but some were taken as 3 horizontal shots but with the camera in portrait orientation. It means the shots themselves are fairly similar to the single shots of the same area, but with much more resolution, so if I choose to print any out, they can be printed much larger.
These attached versions are obviously still reduced to 800px wide.. I can upload a larger version if required.
Thanks for looking.
