The Book That Unlocks the Mysteries of LAB Color
By Kevin H. Stecyk
Many years ago, I purchased Dan Margulis’s book “Photoshop LAB Color: The Canyon Conundrum and Other Adventures in the Most Powerful Colorspace.” At that time, I didn’t understand Photoshop’s channels and certainly didn’t understand LAB colorspace. Being relatively new to Photoshop, I was eager to dive in and learn. When I finished the book, I had an understanding of channels and LAB.

To many people, LAB seems like an esoteric and foreign colorspace. I found, however, that LAB made more intuitive sense than RGB. For example, I know that for the A and B channels, positive values are warm and negative values are cold. I like that the L channel is luminosity. To me, LAB readouts are logical and intuitive.

While I still do some of my work in RGB and occasionally in CMYK, my workflow makes extensive use of LAB. It’s in LAB where I boost or strengthen colors. Once you read the book, you’ll have a better understanding as to why more than one colorspace is used to complete an image.

Dan’s latest book is, of course, even better than his original book. Over time, Dan gained more knowledge through experience, and much of that knowledge has been passed along in his latest book.

In reading both books, I found that some of the supposedly easier chapters were more difficult than some of the supposedly more difficult chapters. Dan’s books require concentration to fully absorb the material. My process with the first book was to read the book cover to cover and then to reread it again. Then, I selectively reread portions where I needed further review. Having the good fortune of being chosen as a beta-reader for his latest book, I read each chapter as soon as it was released. Even with my prior background, I still had to work at fully understanding everything. Furthermore, I often read the chapters more than once.

While the prior paragraph might make the book seem overly difficult, that would be the wrong impression. Instead, you must be prepared to work to understand the material, especially if you are still on the steeper portion of the learning curve with respect to Photoshop. I am not a Photoshop guru. If I can learn the material, so can you.

Is LAB a cure-all or some magical colorspace that solves all issues? No, neither. Instead, LAB provides you with more arrows in your quiver. As you read through the book, you might find yourself occasionally thinking, “I might tackle this issue in another colorspace using a different approach.” That’s perfectly acceptable. Dan’s book is geared toward LAB. So he does everything in LAB to show you some different alternatives. You might find that you combine some of your techniques with his. There are, however, many methods or techniques within LAB that can’t be duplicated in other colorspaces. And, that makes LAB extremely powerful. Dan’s book provides you with additional resources that you might not have possessed.

Having said all that, let’s quickly review the chapters.

*Chapter 1: The Canyon Conundrum*

It’s a quick introduction to LAB. You will see LAB at work with some easier examples.

*Chapter 2: LAB by the Numbers*

Readers begin to understand how numbering systems work and how the channels work.

*Chapter 3: Freedom and Responsibility*

You learn about the power of LAB. One of challenges is not going overboard with LAB. The overall aesthetic you are trying to achieve will determine how much extra color you may decide to add.

*Chapter 4: Too Much is Just Right*

Throughout his book Dan teaches us that it is better to go too far, and then back off the intensity. He presents several methods for doing so. Another key learning is that it’s okay to go too far so long as critical elements of the photograph are kept in check. One challenge when working on images, however, is that we often become desensitized to our own creative work.

*Chapter 5: Knowing Right From Wrong*

Earlier I mentioned that I found LAB more intuitive because positive values in the A and B channels are warm. This chapter takes that whole discussion much further.

*Chapter 6: Sharpening for The Impressionist*

Dan provides a comprehensive discussion on sharpening, including why you might sometimes want to sharpen in LAB.

*Chapter 7: Entering the Forest: Myths and Dangers*

Some common misconceptions and myths are explored. As an example, is the best way to convert to a black and white image simply to use the L channel from LAB? While I won’t provide the discussion, the answer is, no.

*Chapter 8: The Readers Sum It Up*

Here the beta readers contribute some of their knowledge and experiences.

As we enter the second half of the book, the material generally is more advanced. As mentioned, sometimes you may find the more advanced material easier than the earlier material.

*Chapter 9: The LAB Advantage In Selections and Masking*

I found this chapter very powerful because it unleashes how to use LAB and its channels to create very effective masks.

*Chapter 10: The Product Is Red But the Client Wants Green*

For those that often change colors, say of garments, this might be the most important chapter for you. For others, it is more arrows in your quiver.

*Chapter 11: The Imaginary Color, The Impossible Retouch*

LAB allows us to create colors that are impossible, imaginary colors. We can sometimes create these colors to put color back into blown out and overly dark areas.

*Chapter 12: The Best Retouching Space*

For certain types of retouching, LAB has advantages over RGB and CMYK colorspaces. Dan provides some great examples of where LAB excels.

*Chapter 13: The Music of Noise*

Marco Olivotto, another beta-reader, largely wrote this chapter. It was one of the most popular chapters for our beta reading group. The topic, of course, is noise reduction.

*Chapter 14: Command, Click, Control*

I enjoyed this chapter because I learned how to easily create color differentiation amongst items that have a similar color.

*Chapter 15: LAB and Video*

Dan shows how LAB can be used in Photoshop to add more punch to your videos.

*Chapter 16: The Universal Interchange Standard*

Dan provides a discussion on colorspaces, color models, conversions, and calibrations.

*Chapter 17: Blending With the A and B*

A and B channels are used in creative ways for blending purposes. Even though A and B contain no detail, they can be used as blend sources to separate objects based on their color.

*Chapter 18: Canyons, Concepts, and Changes*

In many respects, this chapter is a review and discussion of the prior material readers have been exposed to.

The book contains a tremendous amount of information. For those of you who have read his first edition, you should know what to expect in terms of difficulty and rewards. For those who are new to LAB, this book will be extremely beneficial. At times, you will likely find it challenging, but your prize at the end of the process will be worth your effort. You will have a much better understanding of channels, LAB colorspace, and what LAB can do for you.

For my own personal work, when working with LAB, I am faster and more efficient. And, most importantly, I get much better results.

you will be amazed at what the humble photograph will reveal
By MikeyD
As a beta reader, I was honored to review what I consider the most comprehensive photoshop LAB color correction book to date. It builds upon the first edition and adds new insights and techniques that were developed since that time. Once you understand and develop these new methods, you will be amazed at what the humble photograph will reveal.

you owe it to yourself to get this if you are serious
By P. William Bane
I have bought very, very many books on Photoshop. and the books by Mr. Margulis are head and shoulders better than the others.

First, there is a theory, vs a mindless push this vs that button. Second, there is are lots of first class (and very expensive to print) photos in the book to see (!) how the application of the theory works, or not, as the case may be. Third, Mr. Margulis writes with a first person immediacy that is very motivating.

Having said all these good things, this book gives back in proportion to the time and attention put in, and this is not the deal that lots of people are looking for. If you are serious, you cannot do better.
