I'm giving a talk at Rangiora Photographic Society this coming Tuesday 3rd October. I'm going to be processing some stitched images during the workshop, and if you'd like to follow along on your laptop, here's a link to the source files you'll need!
It's a large file (~600Mb) so it may take a few minutes to download. During the workshop I'm going to use a variety of software; Lightroom, Photoshop, Nik and PTGui. Nik is free, and Hugin is a similar stitching program to PTGui so you may want to get these installed beforehand!
If this doesn't work, drop me an email and I'll sort out another way to get the files to you..
