My favorite new feature in ON1 Photo RAW 2025 is Depth Masks. Why? Depth masks open up new, creative ways to select regions of your photos based on how near or far they are from the lens. The selections are nuanced yet natural, and speed up your editing workflow.

What Is A Depth Mask?

A Depth Mask is a special type of mask automatically made for you by ON1 Photo RAW. ON1 analyzes your photo and determines what elements are closer to the camera vs. farther away. Photo RAW analyzes the depth in the scene and allows you to refine a mask based on that analysis. Like all masks, portions of the photo are revealed (masked white) and other areas are concealed (masked black), with varying levels of opacity in between (masked shades of gray). Also, you can modify depth masks using the other ON1 masking tools, like gradients and brushes.

A depth mask in ON1 Photo RAW does not require your camera to capture and embed depth metadata into your RAW images. The analysis is AI-powered and you can use this new masking approach with any of your photos.

How Do I Use Depth Masks?

Depth Masks are found in the masking panel and you can use them anywhere you can mask in ON1. You can apply a depth mask to an Effects filter, a Local Adjustment, or a Layer. In the masking panel, there is a new icon for the Depth mask. Click the Depth Mask icon and then your photo is analyzed and the mask is created.

By default, the depth mask select elements in the foreground, masking those white or light gray. Adjust the Levels and Window sliders in the making panel to change what is masked. You can push the brighter areas of the mask to the midground or background and limit how much of the areas are affected. Work visually with a mask overlay while refining your depth mask to target just the elements you want to affect.

My recommended workflow is:

• Decide what elements you want to impact with a filter or adjustment

• Click the Depth Mask icon

• Turn on the Mask View using the grayscale overlay

• Adjust the Levels and Window sliders in the masking panel to refine the mask

Once you have your selection, push and pull the filter or adjustment sliders to apply style to the masked area.

Creating A Foreground Depth Mask

Selecting a foreground with a depth mask is straightforward because, by default, the depth masks targets foreground elements. In the photo below, a depth mask is used to apply more detail and local contrast to the cairn and foreground rocks. The workflow for this image was:

• Add Dynamic Contrast to the filter stack and click its masking icon

• Click the Depth Mask icon in the masking panel and turn on the mask view

• Adjust the Levels and Window sliders to limit the mask to only the foreground cairn and rock (no beach)

• Turn off the mask view and adjust the style of Dynamic Contrast (Surreal worked well for this image)

Pro tip: While Super Select AI can select an object or region, a depth mask provides a more nuanced mask with varying levels of impact (notice the shades of gray in the mask below).

Creating A Background Depth Mask

You can target the background of your photo with a depth mask, too. However, you may not be able to affect the background with just Levels and Window sliders adjustments. Instead, apply the depth mask and then invert it. By default, the depth mask will affect elements in the foreground. Inverting the mask switches that to affect the background.

In the photo below, a Sunshine glow was added to the just the background. The workflow for this photo was:

• Add a Sunshine filter to the filter stack and click its masking icon

• Click the Depth Mask icon in the masking panel and turn on the mask view

• Adjust the Levels and Window sliders to limit the mask to only the foreground cairn and rock (no beach)

• Turn off the mask view and adjust the style of Sunshine filter

Pro tip: Invert a depth mask to target background elements in your photo.

Creating A Midground Depth Mask

Midground selections may take a little more work yet are well within reach after a couple of clicks and slider adjustments. Create the depth mask and adjust the Window and Levels sliders. If the elements in the midground cannot be targeted to your satisfaction, invert the mask. Then, continue using the Window and Levels sliders to refine the mask. This is where working visually with the grayscale mask overlay is helpful to visualize what parts of your photo are masked.

In the photo below, a slight brightening was added to the two people behind the bar. The workflow for this photo was:

• Add a Local Adjustment and click its masking icon

• Click the Depth Mask icon in the masking panel and turn on the mask view

• Adjust the Levels and Window sliders so the people behind the bar are mostly masked white

• Refine the mask with a Gradient Mask and Masking Brush to paint out any straggling areas of the mask

• Turn off the mask view and adjust the style of the Local Adjustment

Pro tip: After crafting your depth mask, use the other masking tools to refine the mask.

Conclusion

Depth Masks are versatile and easy to create with ON1 Photo RAW 2025. It’s a great tool to build complex masks quickly and target elements on a given focal plane. Even in cases where Super Select AI can select an object readily, depth masks provide another option for masking.
