The **Brush Mask** tool can be used in either **Paint** or **Erase** mode to add to or subtract from the masked area. Select the Paint mode to apply the mask. Selecting the Erase mode lets you erase masked areas to refine your selection.

#### Here’s how to use the Brush Mask tool: <a href="#h_01ht2pja5c0j3mz4g9dhnnv6cf" id="h_01ht2pja5c0j3mz4g9dhnnv6cf"></a>

Here’s an example of how to use the Brush Mask tool. Let’s add an obvious effect so it’s easy to view.

1. Open an image in Luminar for Desktop.
2. Select the **Edit** tab on the Top Toolbar to reveal the Tools pane and scroll down to the **Creative** tools.
3. Choose the **Dramatic** tool and increase the sliders to high values, making the effect easy to see.
4. Click the **Masking Tab** within the tool.
5. Choose the **Brush** mode in the mask tool.
6. With the Paint button selected, use the brush to paint areas of the image to which you want to apply the Dramatic tool. Masked areas will be indicated by a translucent red mask. This mask is visible while you are clicking to brush. You can also turn it on by clicking the **Mask actions** dropdown and choosing **Show Mask**.
7. As you work, you can easily undo your brush strokes. Simply choose the **Erase** button and paint over the selected area.
8. Continue painting the mask until you get the desired results. Use the Size, Softness, and Strength sliders to control your Brush and Erase tools.
9. If needed, you can refine your mask by using the additional mask controls.

Please note that Masking is not available in Noiseless RAW and Develop RAW tools. Once you apply any adjustments, these tools will automatically switch to their non-RAW versions, and the Masking option will become available.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://support.skylum.com/editing-tools/masking-options/brush-mask.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
