From the Author
Continued......
We've created a work which we feel is unique, and most of the information in the book cannot be found in _any_ other Photoshop book. We've already heard from many of you who had preordered the book, and the feedback is universally positive. One guy wrote to us and told us that he found three pages in the book which justified the entire purchase price. If you read the book, please post your positive (and negative) comments here on Amazon. We promise that we'll work hard to make the book what _you_ want it to be. Thanks for reading/listening! And keep your eyes on this space for more updates/news....

5.0 out of 5 stars The Alfa and Omega of Photoshop: simply indispensable, 15 May 2004

By	R. Clercx "ronald_clercx" (Oostende, BELGIUM) - See all my reviews (REAL NAME)

You are probably an intermediate user of Photoshop, otherwise you wouldn't have found your way to this book. (which is quite sad actually).

You have probably gone thru the usual 'Photoshop Bible', 'Photoshop Wow' and quick and trick literature.

You may be feeling after reading the top heap that you have managed to find out how to create a desired look, but with the nagging feeling that you don't really understand how it comes that three gray channels make up a color image? Or what that darn 'calculations' or 'apply image' do and why they are so usefull.

Ever read a decent manual to 'calculations' (may'be you even never heard of it or never use it) or 'apply image'. I guess not.

Actually it should be the other way around: if you truly understand how channels make up an image, this really opens the way to professional enhancement of an image.

And this is exactly what this book is about: how to use knowledge of channels and alphachannels (masks) to get to the core of every image out there.

Although this is a book about a complex subject, you'll never get a headache, and all the techniques which flow out of the theory are laid out in a very understandable language. And they are very usefull for image compositing, which makes up a great part of image enhancement.

You can use this book to create the masks you want and target the areas of an image which need enhancement, and ever better, you'll feel that you know really understand Photoshop.

It is simply a book which belongs on the shelf of every aspiring Photoshop user.

Although, the book is now quite old, it beats most of the newer books when it comes to decent literature and using Photoshop on a professional level.

The downside: this is a book which is aimed almost solely on RGB channels techniques. True, other colormodes consist of channels as well, but the way they relate to each other can be hugely different to the RGB layout of channels.

Never the less, a classic, even so many years after date in print: it only shows that this book doesn't become dated when certain effects go out of fashion, it is the guide which lays at the very core of Photoshop.

5.0 out of 5 stars The Best Discussion of Digital Blue Screen Techniques, 14 Jan 1998

By A Customer

This is one of the best books on using photoshop for what it was originally designed for - compositing images. Written by ILM alumni David Biedny and digital film production veterans Bert Monroy and Nathan Moody, this is not your standard "how to use photoshop" features walkthrough. It is also not a beginner book. You will not find out what the "edit" menu does in this tome... It is designed for someone who already knows what the tools in photoshop do, but wants to find out how to apply these powerful (yet sometimes misunderstood) features to real world tasks. It extensively covers channel operations (add, subtract, multiply, screen, etc) and how these somewhat esoteric "modes" are useful in compositing images. These guys know what they are talking about from thier years of photoshop and feature film production work. This is the second book from these guys, and remember that they wrote the first-ever book on photoshop, years before anyone had even heard of the program! The book also contains the best discussion of blue and green screen techniques that give better results than some well-known software packages costing thousands of dollars. This section alone is worth the price of the book! Includes a section for After Effects users too. I highly recommend this book to anyone involved in compositing images, whether it be Photoshop, Premiere or After Effects or any similar package on any platform! Chris Athanas Director of Engineering, DigiEffects

5.0 out of 5 stars The definitive book on Photoshop, 10 Aug 2001

By	Mr. Graham Cummings (Yorkshire, UK) - See all my reviews (REAL NAME)

Although aimed primarily at Photoshop 4, the techniques this book describes are useable in any version after 4 (and probably before too). The author's grasp of the subject is second to none, and everything is explained in simple terms. I think you'll probably need some experience with PS first, as its not a straight step-by-step guide. I thought I knew everything that PS could do, until I read this book. I find myself continuously saying 'Doh! oh yeah!' when I've read about the techniques in the book.

Nice one, lads. Looking forward to books you'll hopefully produce in the future!
