As a panoramic (or virtual tour) photographer myself, I was hopeful about this book. It's bound well with lots of glossy photos and an easy-to-read layout. It is the only book (that I know of) dealing with the growing area of 360 degree or virtual tour photography. That in and of itself deserves some credibility.
The author gives lots of step-by-step photos, showing the different camera brackets and tripod heads needed, and covers the various techniques for shooting in-line or full cylindrical virtual tours. There are even a few sidebars with comments from other virtual tour photographers or company owners. The coverage and explanation of parallax errors is done well.
I wish there had been more of an explanation as far as the different software types, the pros and cons of each, expenses involved, etc., although there is a nice section on how to polish up finished images, and what to do to get a good exposure when the room & light you're in prohibits it.
Shooting these types of tours with a fisheye isn't really covered, and even though it's not the most popular way to create a panoramic or 360 degree tour right now, neither is the egg-type of 1-shot method the book does go into detail with.
If you're looking for a book on 360 degree imaging, I suggest this book. The website references and up-close equipment shots, and diagrams of stitching methods is very good. It's not a coffee table book full of breathtaking panoramics, so don't buy it if you're looking for that. (Although there are a few nice landscapes.)It's not the be-all of 360 degree imaging, but it's a great start.
