I use this book as a manual for a 3 day Photoshop class, and for the first time I'm dissapointed with Adobe Press.They saw fit to remove all discussion but a partial page on resolution, one of the most important and difficult topics for a novice to understand. In previous versions excellent examples had been used to discuss this. But this version sacrifices knowledge to further sales by adding chapters on ImageReady. Unfortunately, the rest of the book also misses the mark in many areas. Some examples are poor and would never be done that way in a real world setting. Some chapters completely miss the mark. Version 3 was in depth and had great examples, Version 4 perfected some of that while only sacrificing a solid example of the Pen Tools usage. Too bad Adobe went downhill from there with this version.
