I've taken a stab at figuring out Apple iBooks platform. It's pretty cool tech that let's you mix text, photos, and video into an interactive platform.
I've taken some of my best panoramic photos (and the tutorials I made about them) and bundled them into an iBook.
It's free, it's currently the #2 photo book on iTunes in fact (sweet!).
It only works on an iPad (sorry everyone else, but that's how iBooks author works for now).
I hope you enjoy and are inspired to start shooting your own shots. I'm working on new stuff for this platform and would love your feedback. Please post reviews on iTunes and comments here.
