Why Channels Power Tools
What to know first
Channels Power Tool is, as the name says, a very powerful tool. It allows us to work with Photoshop channels at unbelievable speed and with unseen control and it takes a step ahead of the usability of one of the essential ingredients of every image: the channels. This introductory section is aimed to introduce the characters we’re working with on a daily basis (whether you know it or not) and some concepts that can be an ace in lots of situations.
What Photoshop Channels are.
Within Photoshop we can find several kinds of channels, but we will deal only with color channels, that compose our image (Grayscale, RGB, Lab, CMYK, HSBcreate usually), and alpha channels. Channels Power Tool uses these channels to create a selection.
We can give a brief definition of a channel as “The representation of a selection in grayscale.“
“The keyword here is “representation.” Everyone knows how useful a selection is, maybe what is not so clear is that Photoshop gives us several ways to visualize (and therefore modify it). We are used to visualizing a selection with the so-called “marching ants” or maybe in Quick Mask mode. But it is also possible to visualize a selection as a grayscale image, like every time we use a layer mask.
Channels work exactly in this way: they show with a different shade of gray if a given pixel is selected, and how much. In RGB an entirely white pixel (when we look at a particular channel) means “this pixel is (totally) selected,“ while a pitch black pixel means “this pixel is (totally) not selected.
Guess what a medium gray means? Let’s try with an example: create an RGB file and manually paint the R (Red) channel completely white, then paint G (Green) and B (Blue) pitch black. How our file is going to be? Exactly, pure red. The values of our channels will be R=255, G=0, B=0. Doing this we ask Photoshop that we want only and comprehensively select the red component of the file.
Let’s take a more common example: a landscape with a blue sky on a bright sunny day. Try to visualize how channels will be in the sky area. Blue
At the very beginning, it’s hard to pre-visualize the structure of each channel, and you need to check them one by one toggling the visibility in the Channels panel. Here it comes CPT, which lets you, with literally just one click, see the structure of each channel at a glance. Not only in RGB or the color mode you are using, but in all three main Photoshop color modes (RGB, Lab, and CMYK) at the same time.

Image>Apply image is one of older Photoshop functions and let us copy-paste channels or layers (our source) on channels, summon players or layer masks (our destination). You can change the opacity of the source you’re applying its blending mode or you can also mask it choosing a channel.
The Apply button of Channels Power Tool summons this function that, for
What is GCR and how it can be useful to you.
GCR means Grey Component Replacement.
This concept works in CMYK color mode, where we can obtain the same color in different ways using different values combinations for the four primaries. Everything became clear if we consider a color composed of various elements, dealing with luminosity, tint, and saturation. Luminosity is the equivalent of the gray strength of a color: how much dark or bright we perceive this color.
We can have two colors with the same tint and saturation (i.e. a particular red) but different luminosity. Let’s call them a dark red and bright red for ease sake. What distinguishes them is the luminosity. In CMYK we have the theoretical possibility to obtain a gray in two distinct ways: blending proper quantities of CMY or using just the K.
This can take to a lot of issues in we are going to print in offset, but in our hypothetical example let’s imagine things work in a perfect, mathematical way. Let’s say we want to obtain a medium gray. In RGB we would only have R=128 G=128 B=128. In CMYK (considering a Coated FOGRA39 profile) we can reach this result in (at least) two different ways: with just a K=50, meaning we have C=0 M=0 Y=0 K=50, or leaving K=0 and using only CMY components like this: C=58 M=48 Y=47 K=0. Now we got lots of different possible combinations, adding a little K and subtracting CMY in a right proportion. This is exactly GCR: how we transform our gray component when converting to CMYK. A low GCR will use a lot of CMY and small K (K will be lighter), a high GCR will use a lot of K and less CMY (K will be darker) while a medium GCR will be something in the middle.
This explanation leaves a lot of dark areas in explaining this concept, but nonetheless, let us understand how a custom GCR could be useful: to obtain a K darker or lighter, that we can use as a mask, a selection or anything we could think about.
