Key Insights
- Lightroom's Adjustment Brush tool allows users to apply specific changes to selected areas of a photograph. In this tutorial, the tool is used to darken the sky and turn flowers gray.
- Images can be imported into Lightroom through the Library module, which allows users to navigate to the location of their files and import with a click.
- The Adjustment Brush tool can be found under the Histogram panel. Its effects range from exposure adjustments to flow modifications, with an Auto Mask feature for brush precision.
- The size of the Adjustment Brush can be altered with the right and left bracket keys. This feature allows users to control the area of effect when applying changes to their photo.
- Masks, which highlight the area of effect of the Adjustment Brush, can be viewed by clicking on the circle that appears on the photo after the brush is used. The color red indicates the mask when the cursor hovers over the circle.
- The saturation of photo elements can also be adjusted using the Adjustment Brush. In this exercise, the saturation of bright purple flowers was decreased. The red mask color assists in identifying the area of effect while brushing.

Exercise Overview
In this exercise, you will experiment with the Adjustment Brush tool to apply very precise changes to a photo. Specifically, we’re going to “brush” a sky darker and “brush” flowers grayer.
The Adjustment Brush Tool
- If you have not imported the photos that were imported in Exercise 2E:
- Go into the Library module.
- At the bottom left of the screen, click Import.
- In the dialog box that appears, on the left under Source, navigate to Desktop > Class Files > Lightroom Class and select the Develop folder.
- At the top, above the photos, make sure Add is selected (highlighted).
- On the bottom right, click Import.
In the Library module, select the Hampton Court Palace & violets photo (_CAS4948).
Press D to go into the Develop module.
In the Navigator panel, click on FIT if it is not already highlighted.
Under the Histogram panel, click the Adjustment Brush tool
.

will decrease the brush size. Brush the entire sky (try to avoid brushing the buildings and trees, though it won’t cause much damage).
When finished, click the Adjustment Brush tool
again to deselect it.
Click the Adjustment Brush tool
to select it again.
On the photo, locate the circle
, which corresponds to the sky’s mask.
-
Click on this circle
to reveal the mask.
NOTE: A black dot will appear inside the circle
to show it’s activated
Hover over that circle for a few moments, and the mask will be indicated by the color red (appears pink/light red).
Next to Exposure, drag the slider to − 3.00.
-
If you’ve missed some spots, use the Adjustment Brush tool
to brush them now.
If you’ve accidentally brushed too much, press Opt (Mac) or ALT (Windows) and brush over those areas to subtract from the mask.
Notice that some buildings and trees have a slight halo where the sky meets them. We need to tone down the exposure.
In the right side panel, set the Exposure to − 1.60.
Click the Adjustment Brush tool
to deselect it.
At the bottom of the screen, click the Before & After icon
to examine your work. Neat!
At the bottom of the screen, click the Loupe View icon
.
Adjusting Saturation Via Adjustment Brush
Let’s decrease the saturation of the bright purple flowers.
Click the Adjustment Brush tool
.
In the panel that appears, from the Effect menu, select Saturation.
Below that, drag the Saturation slider left to − 20.
Press O to show the red mask color as you brush.
Brush some of the flowers.
Press the O key again to hide the mask and to see the flowers desaturated.
Press O again to reveal the mask.
Brush the rest of the flowers.
Press O to see the changes. Neat!
Deleting Adjustment Brush Masks
To get rid of one of the adjustment masks that you brushed onto the photo, click on the circle corresponding to the sky’s reduced exposure to select its mask.
Press Delete on your keyboard to delete it.
- Delete all the remaining masks:
- Click on the circle
on the flowers.
- Make sure it now has a black dot
inside it.
- Press Delete to delete it.
We’ve now reverted to the original photo.
As you’ve observed in this exercise, the Adjustment Brush tool easily makes nondestructive, reversible changes to a photo. Good stuff!
