The site now has two versions of the book's example files. The first is a relatively slim 5MB version, which includes only the Lightroom catalog without the source images. The big-tuna version, which weighs in at 308MB, also includes all the source images. You'll find them both here.
I've now posted a Lightroom catalog of the example images used in the book. So buyers of the book can download the catalog, open it in Lightroom 3 and follow along as they work through the book's examples of how to sort, find, tag, and adjust photos. Thanks to Lightroom's metadata magic, you'll be able to see all the keywords, flags, labels, and ratings used for each image in the book.
Take a look at the instructions on how to download the catalog file and open it within Lightroom 3. (The instructions page also includes the link to the example files.
As always, if you have any suggestions as you start using the files, feel free to send me a comment using the comment form on this page or on the instructions page.
