This is a great book for balancing understanding how to achieve an outcome with how to use the software. I also have the very popular Scott Kelby book but don't like it much. He is a bit like Marmite and you can guess which camp I'm in. I find his style wearing and the book quite disjointed and I feel like he's trying to show the reader how clever he is all the time. This book flows much better, is more outcome focussed and is an easier read. With this book plus the excellent Digtal Negative and Digital Print books by Jeff Schewe you will be fully equipped to achieve pretty much anything that can be achieved in Lightroom.
