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.

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!

I've always wanted to get my teeth into a good, no holds barred how-to book on using Photoshop's channel operations, but none measured up until now. I always felt the Photoshop manual, and other 3rd party how-to books fell very short on using channels. Dave, Bert and Nathan, authors of this book, have done an excellent job of introducing you to the basics, and then taking you way beyond where the others leave off. They stick exactly to the topic of channels, always giving lots of examples and experienced tips from their work. You'll learn about RGB and Alpha channels, layers and layer options, masks, paths, blue/green screen techniques and more. Sink your chops into this one, byte off a big chunk, and feed your brain. BTW, I bought this book like everyone else, I just think it's that good, and they deserve the recognition for their hard work.

David Biedny and Bert Monroy are a couple of Photoshop gurus, and in this book, they team up with Nathan Moody to bring you the definitive book on using the venerable program's channel operations. An entertaining and educational introduction by Biedny discusses pre-digital compositing technology, a history of Photoshop, and includes sections entitled Why Are You Reading This? and Monkeys Push Buttons, Humans Push Their Brains. The chapters proper cover channels, alpha channels, layers, calculations (Biedny hates what Adobe did to calculations in version 4, so uses a hypothetical Calculations box for part of the chapter), paths and blue screen/green screen. At 226 pages, it doesn't seem very long, but it's got more good stuff than many books twice as long, including lots of groovy color illustrations.

I have read a good few books on Photoshop Channels,this is the oldest and the Best without doubt,to Quote Neil Barstow "theres no going back after reading this book". It was written around the time of Photoshop 4, but , the information contained within is the very best and from the 3 guys who were there at the conception of Photoshop,its not cheap, but it should be on your bookshelf if your serious about Photoshop Channels.

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!

Aimed squarely at the expert user, this guide discusses in-depth Photoshop channels, layers and calculations, as well as features such as blue-screening. If you're an experienced user and want to push Photoshop beyond its usual limits, you'll find this fascinating.
Presented in full colour, the authors explain in detail how to implement advanced techniques such as the manipulation of alpha channels. Their breadth of knowledge of Photoshop is quite staggering, and you always feel that the book is a master class to end all master classes.
If you're ready to take a quantum leap onto another plane of Photoshop utilization, then this is the book for you. It shows you how to manipulate what, to the majority of users, are Photoshop's hidden talents. This isn't just a tech-heads reference manual, but a thorough in-depth discussion of these advanced techniques. Only Photoshop gurus need apply.

I'm only to page 54 and have already gleaned enough new techniques to speed up my work tenfold...
This is the first really valuable book I've found on advancing my skills in Photoshop (and I've been hacking around in Photoshop since the 2.5 days!)
...and I'm no "newbie" to the field -- I've been producing video, multimedia, CBT, websites, etc. for 6 years and am amazed I've been struggling this long without discovering this book.
Here's a little gem from the book... did you know that when you reduce a color image to grayscale you are handed a fixed "fast approximation to luminance" (30% red, 59% green, and 11% blue)?... Want more control? Create your grayscale with the Calculations command and use your own percentages for the best results.
This is an awesome book and a must for any serious graphics professional!!!
I love it!

Another great book from New Riders Publishers. This book is thin to win. If you want to go beyond the basics in Photoshop and get a deeper understanding of how to use channels to create layers, masks, selections, etc., then this book is an educational experience. I was dissappointed though in that a CD w/lessons wasn't included. New Riders Photoshop books usually have a CD w/lessons. Oh well, it still paid for itself. Filled with lots of time saving advice and warnings of things to NOT do. Understanding the basics of the Photoshop engine, the channels of colors, layers and how to correct composition, color, masking...hey, what can I say...if it's published by New Riders, a subsidiary of Macmillan, I'll buy it because unlike the stock market, the value of this book will not fall, it can only go up!

Most books teach you to move forward and backward thru photshop. This book shows you the possibility of moving sideways. It shows a variety of methods of generating complex masks and selections thru relativley simple repeatable processes. By learning these processes, you can reduce up the time it takes to generate complex edges and increase the number of artistic choices available in the all too often crunch of deadline, and improve the quality of your work. With this book you can actually begin image-processing, instead of just pixel-pushing.
