I'm writing an eBookl to be sold on the Internet called "Introduction to Virtual Photography" for the people interested in getting into Virtual Photography and photographers like many of us iPIX users who switched to other products.
 
I'm trying to provide an overview of the basic capture techniques, popular cameras & lenses, stitching tools and viewing methods.
 
I'm including a basic description of some of the more popular stitching programs and although I've played with the Demo of RealViz Stitcher Unlimited DS quite a bit, I'm not good enough at it to make informed comments about it.  
 
I'm interested in talking/trading e-mails with some one who switched from IIS to RVSUDS and has gotten into some of the more advanced features & functions and getting your comments and impressions.
 
Any help would be appreciated
