It's easy to edit the photos with Photoshop tools and its plugins.

Language has evolved to the point where we use photoshop as a verb. We often hear phrases such as “photoshop something into the picture” or “try photoshopping it out.” This primarily means using masking tools and layers in photo editing software to transform an image. Photoshop software has indeed given the world a powerful set of tools to transform images in unbelievable ways. It has led photography to a whole new world of possibilities. However, now there are a lot of editing software applications besides Photoshop that offer a variety of helpful masking techniques, taking the game even further. Luminar, with its friendly clutter-free user interface and all the options you need, is a great photo masking tool. It’s also an example of how you can go beyond the basics and conquer new horizons when masking photos.

Why use masking?

Non-destructive transformations

Masking is non-destructive. This means that you can undo the changes you make to a photo. Also, professional photo editing software usually has the option of adding layers. Any changes, including masking, can be made on a new layer on top of the existing photo, leaving the original untouched. That’s why masking is a great tool to use on different layers of your photo, which allows you to experiment with your photo’s final look. It’s a great way to see changes and go back if you don’t like them, all without damaging the original photo.

Compare changes

By clicking the eye button in Luminar, you can see even the slightest changes that you’ve made. You can also use the split screen option to see your progress, and decide which areas that you need to change next. Any photo masking software will let you easily see the difference between the original and edited versions of your photos.

Edit only certain areas

Was the sky cloudy on the wedding day? If so, you can use masking tools and transform the sky to look as beautiful as the rest of the scene. Rescue your photos and change them into works of art.


Your imagination knows no limits. You can edit someone in or out of a photo and add objects, animals, and landscape elements, altering reality completely. Masking photos allows you to become a god.

Luminar tools

Masks allow you to hide or obscure parts of an image. They let you combine the contents or results of one layer with your base image. Layer masks allow you to use powerful painting tools to control the results. The more you work on combining multiple images, the more you’ll use masks.

Luminar offers four types of masks. To access them, create a new adjustment layer and click on the brush.

Gradient mask

You can apply a gradient mask to create a gradual blend, or gradient, between two areas on an image or two different layers. Gradient masks are defined by a horizontal, vertical, or diagonal line from which the mask is gradually applied, helping you make the transformation smoother. By clicking the visibility button you’ll see the area where the gradient has been applied.

Luminosity mask

A luminosity mask is based on the brightness of pixels in the image. It automatically applies light to lighter areas while keeping the darker areas dark. And it does so in a subtle way. You can start by applying any preset you like to a photo. Then you can use a luminosity mask to start masking the photo. This may take a few minutes. Use the eye icon or the split screen to see the difference.

Radial mask

A quick and easy way to highlight an area of your photo is by using a radial mask. A radial mask can be applied to a layer and creates a circular mask radiating from the point on the image where you apply it. You can make a radial mask oblong or stretch it as you need.


Use a brush to correct the finer parts of masks or to apply your filters so they cover only certain areas. You can use brush strokes to add or subtract from a mask. In order to see where you’re applying changes, you can click on the eye icon. This will show you in red the areas of your photo to which the mask is applied.

Practical guides

Here are some practical guides on how to use masking tools to your advantage. With some simple steps you can create images like those in magazines.

How to use layers

In any masking software, layers are your canvas. You don’t have to apply changes directly to your photos. When you have a layer, all changes can be done on it so you can see how different effects will look on the photo in a non-destructive way. You can add a new image layer (your own photo) or a new adjustment layer (making changes to the existing photo).

How to use masking software

In order to apply filters to specific areas of your photo, you can use masking layers and brushes. Some of these tools and their specific effects are all listed below. In order to apply a mask to a layer, add a new adjustment layer and start working.

This option lets you fill the area entirely with the details of your filter, creating a mask over your image. After that, you can use the brush tool to paint over the mask and subtract from it.


This option inverts the opacity and transparency values of any mask that you’ve created. Look at the little mask icon next to your photo and see how the values change when you click it.


This is the opposite of the fill option, which completely unmasks your image. After clearing the mask, you can use paint brush or gradient tools to add details back to the image.

These are only some of the tools you can use.

How to edit someone into a picture

When editing someone into a picture, remember that both of the pictures that you’re trying to merge should have similar exposure, lightning conditions, and so on. Ideally, they should be taken in the same type of landscape and weather. A sunny face will look bad edited into a dark room. Technically you can merge any two photos, but the results may look unnatural. When you have two visually compatible pictures, for example a landscape and a shot of a person outside, you’re ready to start working on masking photos.

Follow the steps below to edit someone into a photo:

  1. Open the picture you would like as your background.
  2. Click the + icon in the Layers tab and select Add new image layer. Or click Layers > Add new image layer from the top menu bar.
  3. Then, select the photo of the person you want to edit into your background picture.
  4. Click the little brush icon on the new layer and choose the Brush tool.
  5. Start to paint over the person and you’ll see them gradually appearing on your background.
  6. Regulate the Size, Softness, and Opacity of your brush to paint the contours of the person and make them as realistic as possible. Correct any damage done so everything appears natural.
  7. Export your photo.
How to replace a background

Let’s suppose that your picture is perfect apart from the background. Maybe the sky wasn’t ideal on the day you were taking shots or you weren’t able to wait for that perfect sunrise. There’s a way to salvage your shots.

  1. Open a photo that needs a new sky.
  2. Click the + symbol at the top of the Layers panel and choose Add new image layer. Or click Layers > Add new image layer from the top menu bar.
  3. Navigate to an image on your computer that has a sky you want to add and click the Open button to add this image to your document.
  4. To add the sky image, one technique is to apply a gradient mask, which will have the effect of pulling in the sky with more emphasis on the upper part of the image.
  5. Resize or move the gradient as needed for the best fit and click Done to apply it.

You can experiment with masks as you like. For example, this image was made with the help of the radial mask.
