Well, I decided to take a little trip to a local book store and look at the various PS CS4 books that are available. I grabbed a few that I have heard about and/or stood out, and I wanted to comment a bit about each of them and why I picked Martin Evening's book.
Martin's book is a true reference book. It's huge, about 675 pages or so, and it's a very thorough book. I like the smaller things about the format as well, from how he makes references to various pictures on the page like Figure 5.55 (Fifth chapter, fifty fifth image, always on the same page), to how each chapter as a color assigned that can be easily flipped to as the colors are on the top of the pages and can be easily seen and accessed when the book is closed.
I appreciate how he presents the information. It's broken down and again very detailed. What I appreciate is that he does not use any humor in the book. Humor has it's place and time, and a reference book should really not have it, in my opinion. He sticks with a good description of what the topic is all about, and explains how to use and where to find it.
I thought I saw the number somewhere, but there are roughly about 2000 images in this book. You can see by example what he is referring to. May I also say that the publisher is a very good one and the actual quality of the book is excellent.
I'll eventually write a review of the books that I am going to mention, so I'll be concise with the review:
Richard Harrington's Understanding Adobe Photoshop CS4: I like the way he presents it very well. I was going to get this book. But the book is about 3/4" thick and I didn't feel that it was worth it as it retails for $50.
Scott Kelby's The Adobe Photoshop CS4 Book for Digital Photographers: Since his CS4 book wasn't available, I grabbed his CS3 book. Again, it's about 3/4" thick, which wasn't great. But this is the prime example of a person trying to use too much humor. I'm not going to get a reference book to get a laugh - I'm trying to understand how the program works. Plus he uses a "Step 1 - Do this, Step 2 - Do this" approach with what he's talking about throughout the book. I don't like that format. Again, for $50, I didn't feel it was worth it at all, respectively.
Adobe's Adobe Photoshop CS4 Classroom in a Book: In some respects, you can't go wrong with getting the manual for how to use a program directly from the maker's of it. It presented the information well. But again, the book was the same size as the last two, and this book retailed for $55. I would like a certain value and content for what I am paying.
All of the books mentioned above included a DVD for extra information, included images that were in the book. Since I haven't accessed every DVD, I will say that Martin's DVD included many good things in them (nearly 2GB of information!), including images, video tutorials, bonus PDF chapters, PS shortcut lists as PDF, and more.
I highly recommend this book. I didn't know a thing about Martin Evening until I picked up his book and did some research about him. I am very happy that I purchased Adobe Photoshop CS4 for Photographers.
