Useful book - spends a lot of time on using Adobe Lightroom - which is no bad thing as it refers to work-flow & time-saving features. Interesting links and use of commentary by people active in stock photo industry. Like the emphasis on quality control.
Not too far into the book but it's in typical Scott Kelby style. WARNING Read the first couple of chapters about setting up your files & folders before you use the software. You'll be glad you did. Very much worth the money, this book is essential to get you up and running with Lightroom.
