Well, im a beginer at photoshop and have the version CS (you can still use all the things in the book even though it is meant for version 7). I have no manual for it so borrowed this book from the liabary. Its really good, as although it teaches you some strange things, you could use the tips for many other purposes. Im so glad I got this, it has been a heap of heap. I would recommend this.
