When I first got Photoshop 7 I really didn't know much about it, however after I bought the Photoshop 7 Savvy book I became much more experienced with Photoshop 7. I was able to explore new areas within the Software that I would have never discovered on my own. There are lots of good tutorials for advanced layering techniques and advanced selection tools that can be very useful for the first timer in Photoshop.
The only thing that kept me from giving this book 5 stars is the fact that it did not explore much into advanced filtering techniques. There are so many interesting effects you can create using the filtering tools and this book hardly covered any of them. Other than that this book is great.
