I don't actually have the Kindle edition, it is possible to get electronic versions for other platforms.
This is an outstanding book. There's been another update since I read my copy, so I need to read it again. Actually, that's another good reason to buy this ebook, you do get updates as the book expands and improves!
When I was reading it, what I was thinking about were all the articles in main stream magazines about how to accomplish `X' with that other photo manipulation program. This is a book on the software that I actually use that is letting me know how to do cool thing `X'.
I subscribe to several photograph magazines, and I have yet to see a tutorial talking about how to do HDR with DigiKam. Even in general HDR articles, DigiKam never seems to get mentioned. This book talks about HDR with DigiKam, and so much more, HDR is just one example. In a way, it's like having your own clipping service. Here's a collection of all sorts of cool things you can do with DigiKam that you may or may not have realized.
