Masking is the secret weapon behind many jaw-dropping designs, making it one of the most powerful techniques you can master in Photoshop. It lets you blend images seamlessly, create precise cutouts, and apply selective edits without permanently altering your work. It’s the ultimate tool in your editing arsenal.

The best part? Masking in Photoshop is easier than it looks, and once you understand how it works, it can completely transform how you edit your photos and designs.

How to create a Layer Mask in Photoshop

Keep the original layer intact

Unlike Eraser, which permanently alters a layer, Layer Masks in Photoshop allows for non-destructive editing and makes Photoshop one of the best image editors. A tool like Brush can remove anything from a layer to reveal the layer beneath. And since Layer Masks are non-destructive, you can remove the mask at any point without affecting the original layer or pixels.

Here’s how to get started with Layer Masks in Photoshop:

1. Import a photo in Photoshop — this will automatically create a layer for that photo. However, a second layer is required for masking so another photo can be imported orcreated in the app.
2. Drag the layer you want to mask to the top in the Layers panel.
3. Select your top layer, then select the Layer Masks tool at the bottom of the Layers panel.

At this point, you should see a white box attached to your image layer with a chain icon. You’ve just created a Layer Mask.

How to edit a Layer Mask in Photoshop

A non-destructive way to edit

Editing a Layer Mask allows you to precisely refine your photo or design. There are endless ways to modify and apply a mask, but advanced masking can get quite complex, so I’ll stick to the fundamentals.

Think of a Layer Mask in terms of opacity on a scale from solid to transparent. In Photoshop, white means visible (solid), and black means invisible (transparent). To start, your mask is solid, but when you start swiping a brush tool over your layer, those areas will become transparent.

With non-destructive editing, whatever you make transparent can be undone by toggling between white and black, effectively removing and restoring areas of a layer.

Here’s how to edit your Layer Mask in Photoshop:

1. With the top layer selected, click the white box to select the layer's mask.
2. Select the tool you want to use for masking. I recommend starting with the Brush tool because it’s simple and easy to modify.
3. To start making parts of the mask transparent, brush over them with black. Select the Foreground/Background tool and click the little arrow to bring the black box to the front.
4. Now, you can start brushing over the image until the bottom layer starts peeking through. Remember to use the zoom-in function for more accuracy. If you want to restore a transparent area to solid, click that little arrow again, so the white box comes to the front, and brush over the image.

The mask will then start to take shape. It’s one of my favorite techniques for blending Photoshop fonts into my photos.

How to control Layer Mask transparency in Photoshop

Transparency masking is essential

Adding and removing transparency are Photoshop masking basics — but there’s more to it. If white is solid and black is transparent, the gray spectrum between them will produce semi-transparent masks. There are several ways you can control a mask’s transparency:

1. Select the top layer's white box again and choose the Brush tool. Make sure to click that little arrow so the black box is at the front.
2. The quickest way to control the mask's transparency is through the Opacity setting in the top panel. Drag the slider down.
3. Brush over your image to create a blended effect.
4. You could also change the colors of those little boxes in the left panel to gray. Click on the front one (in this case, the black one), choose a gray shade from the Color Picker, and hit OK.
5. Brushing over the image with gray will produce a similar effect as the Opacity method. The bottom layer will peek through, but the top layer is still visible.

Follow the same steps above to restore the transparent areas but prevent them from becoming completely solid. Click the little arrow in the left panel to bring the white box to the front, then reduce the Opacity or select gray from the Color Picker. Brushing over the layer will semi-restore the transparent areas.

More Layer Mask controls you should know

Now you have the basics down, here are a few quick tricks to master masking

First, the Invert control. Remember that white box on the Layer Mask in the right panel? When you hit Ctrl + I (Cmd + I on Mac), it will turn black and invert the mask, meaning the whole selection gets swapped around. This is very useful for fixing errors or gaining a better perspective of your overall mask design; just remember to invert it back.

Also, the little chain icon between your photo and mask serves a purpose. When the chain is visible, the mask is linked to the image, so you can move the layer, and the mask will stick to it. Clicking on the chain icon will unlink it, meaning the mask will stay put if you move the layer. The mask can be moved independently.

Masking made easy in Photoshop

Although we didn’t quite create a masterpiece in this demonstration, masking in Photoshop is a powerful tool that will unlock endless creative possibilities. Start with these basics, mix things up as you go along, and you can create stunning visuals in no time.
