Steve Douglas reviews iMovie HD 6 & iDVD 6: Visual QuickStart Guide, and says some very nice things:
Jeff Carlson has written and published a superb book designed to get the editor in either of these applications up and running in very little time and as painlessly as possible.
The writing is clear and easy to understand even for the complete novice and is beautifully illustrated by both colorful graphics and photographs.
… The bottom line is that what we have here are 295 pages of superlative writing allowing the editor to climb the ladder towards mastery of both of these applications. I wouldn’t hesitate to recommend this book to the new editor or to the teacher whose classes are in need of just the right manual.
