Chapter 15, "Using Lightroom on More Than One Computer," is necessary when you use one computer such as a laptop out in the field, and another in the studio. The question then becomes how to sync them. Here you will see what you need to do to keep them all running smoothly.
Chapter 16, "Archiving Your Images and Catalog," shows that while backing up is important, the ultimate goal is to have an exact duplicate of your catalog and all of the image files on multiple media and in multiple locations. Here you will see how.
D-65's Lightroom Workbook provides a firm foundation on which you can base all of your Lightroom work. It is very easy to read and progresses in an orderly and logical manner. It is very systematically done, and very easy to understand by any level of user.
What I like about this book is that it doesn't just tell you what to do. It gives the reason and logic behind all of the decisions that were made. Even in the early going, when talking about getting better captures, it explains the smallest details about why you should overexpose in digital and why one color space is better than another.
Adobe Lightroom is a necessary product if you want to manage your digital workflow, but if you don't use it correctly, you will end up being inefficient and just working slowly. If you want to truly become efficient in your digital workflow, then you really need D-65's Lightroom Workbook and I very highly recommend this book.
