In fact, with the release of 2.8, Gimpshop has become preferred software for photo & image editing among more professionals than ever. Layers, channels, masks, filters, levels, advanced pattern matching—the remarkable feature list of Gimp is equal to Photoshop in every way except one: the price. The bottom line is, Photoshop is not the only software you can use luminosity masks. Among other software that support the use of luminosity masks are GIMP (freeware) and Affinity Photo, which has a slightly different way of applying luminosity masks. My reviews of the best photo editing software available for 2019 tested from the perspective of a total beginner. For Mac and PC. Masking, other tools and why as well. Other industries besides photography use Photoshop as editing software too such as graphic designers, computer techs, bloggers, etc. Learn all about clipping masks in Photoshop with our step-by-step guide. You'll learn what clipping masks are and how they work, how to create a clipping mask in Photoshop, and how to use a clipping mask to hide different parts of a layer and fit images into shapes!

Several years ago a friend of mine asked me to teach him how masks work in Photoshop. This is my incredibly late response.

We’ll go over the basics of what masks are, what they’re used for and how wielding them properly will take your Photoshop skills to an entirely new level.

What Is a Mask?

Layers are probably the single most important addition to Photoshop since the original version, but layer masks are a close second. I would posit that until you thoroughly understand how and why to use masks, you simply don’t understand the power of Photoshop.

The term “mask” isn’t immediately understandable to someone outside the realm of graphic design. At its simplest definition a mask is a way to apply something to a very specific portion of an image.

There are two primary types of masks: clipping masks and layer masks. These two tools are closely related in concept, but very different in application. Let’s start by discussing layers masks, which are generally what people are referring to when you hear them discuss Photoshop masking.

Layer Masks

A layer mask is something that you apply to a given layer to control the transparency of that layer. Where layer opacity controls the transparency of the entire layer at once, a mask gives you more precise controls over very specific areas. If you want the entire layer to be at 30%, you would lower the opacity, if you want just the left side of a layer to be at 30%, you would use a mask.

When you add a mask to a layer, it covers the entire thing with an invisible grayscale canvas. There are ways to see it that we’ll check out later but just know that as a general rule, applying a mask to a layer won’t cause any immediate visual differences unless you have an active selection at the time.

On this invisible canvas, you can paint white, black or any level of gray in-between. The color that you paint tells Photoshop how opaque to make the pixels at that point. White means 100% opacity and black means 0% opacity.

With this in mind, try to imagine what the mask below would do to a layer:

As you can see, if our mask was all white with the three circles shown above, we would have a completely visible layer where in all the white areas, and spots of transparency in the circles. If we apply this mask to a layer, this is the result:

Clipping Masks

Clipping masks are very similar to layer masks only they use one layer to determine the transparency of another. In this scenario, you stack two layers on top of each other with the bottom being the determining factor of the transparency of the top.

Instead of using black and white values though, clipping masks simply borrow transparency from the layers used to make them, namely the bottom layer. If the bottom layer has some areas that are opaque and some areas that are transparent, a clipping mask will apply these values to the top layer.

This one is hard to explain without an example, but becomes crystal clear when you see it in action. Let’s use the two layers shown below and say that our goal here is to cut or “clip” the wood layer to be in the shape of the letters. Notice that, at this point, the wood is the bottom layer and the text is the top layer.

To achieve the effect that we want, simply swap the position of the layers so that the wood is on the top, then go to the Layers menu at the top of your screen and select “Create Clipping Mask” (Command-Option-G). Voila, we now have the effect we were going for. Where the text layer was opaque, the wood layer is now opaque and where the text layer was transparent, the wood layer is now transparent.

There’s some really interesting functionality here. You can still position and make changes to each of the two layers independently. By dragging around the wood layer, you move the position of the texture inside the bounds of the letters while the letters themselves stay stationary.

Also, you can apply layer effects to the compilation via the bottom layer. For instance, here’s what happens if we select the text layer and add an Inner Shadow.

Clipping masks fun, functional and underrated, but the truth is that layer masks are far more common in every day use. The information above should be enough to get you off and running with clipping masks so from here on out we’ll focus purely on layer mask functionality.

How Do I Make a Layer Mask?

Now that we have a strong grasp of exactly what masks are and how the two different types of masks differ, let’s see how to create and work with a layer mask.

The first thing we need is two layers. I grabbed the two images below from photographers Adrian Durlea and Erik Soderstrom. The shack image is on the bottom and the fire is on the top.

The general idea here is to take some, not all, of the fire and apply it to the shack. The first step is to stack the two images as we see above and set the fire layer’s blending mode to Screen. This will make all of the black pixels transparent, which blends the two images together nicely.

With that one change, this is already a pretty decent image! Let’s say though that we want to only have fire near the door of the shack. To accomplish this, we’ll need to add a mask to the fire layer. Select the fire layer and click the mask icon shown in the image below.

Now, with the mask selected in the layers palette, we grab a soft, black brush and paint out the portions of the fire that we don’t want to see. As we do this, the fire begins to disappear. To bring it back, we simply paint white.

As you can see in the image below, with just a little painting, our fire is now much more centralized to the portion of the image that’s already lit up and therefore looks decently natural.

To see the actual mask, Option-Click (Alt-Click on a PC) on the little mask preview in the layers palette (Shift-click to hide the mask completely). After painting out some of our fire, this brings up the following:

Notice that we’re not just constrained to hard edges. The beauty of masks is that you can do anything you want with them as long as you can pull it off in values of gray. This means you can paint, clone, create and fill selections, copy and paste, and all kinds of other actions you perform on the main canvas.

Why Not Just Erase?

Upon first learning how to use masks, most rookies think the same thing: “I can already do all of this with the eraser tool.” Wrong! In fact, as far as I’m concerned, once you learn to mask, you should literally never pick up the eraser tool again because it tends to be so destructive.

What do I mean by destructive? Think about what happens when you use the eraser tool: it erases pixels. Mind you, it doesn’t hide them for a while until you want them back, it “destroys” the pixels. The changes that you make by deleting portions of a layer are permanent and can’t exactly be tweaked later.

This is simply a horrible way to work. With every new iteration of Photoshop, Adobe gives us more and more ways to make non-destructive edits, meaning those that don’t truly alter the original pixel data. For instance, Filters used to be a permanent and destructive change, if you blurred a layer, it was stuck that way! Now, with Smart Filters,
