How to Use the Selection Brush Tool for Precise Hand-Painted Selections

Why the Selection Brush Tool Deserves a Place in Your Toolkit

Some selections are straightforward — a clear blue sky, a person standing against a plain wall. But what about those tricky situations where automatic tools struggle? Perhaps you want to select just your granddaughter's face in a busy playground photo, or isolate a beloved pet curled up on a patterned blanket.

That is where the Selection Brush Tool in Photoshop Elements shines. Unlike the Quick Selection Tool or Magic Wand, which rely on colour and edge detection, the Selection Brush lets you paint your selection by hand, stroke by stroke. You have complete control over exactly what gets selected.

This tool is particularly helpful for family photo editors who want precision without complexity. Let us walk through how to use it effectively.

Finding the Selection Brush Tool

The Selection Brush Tool lives in the Advanced mode toolbox, which gives you access to all of PSE's editing power.

  1. 1Open your photo in Photoshop Elements and switch to Advanced mode using the mode tabs at the top of the Editor window.
  1. 1Look at the left-hand toolbox and find the Selection Brush Tool. It may be grouped with the Quick Selection Tool — click and hold on that tool icon to reveal the flyout menu.
  1. 1Select Selection Brush Tool from the flyout.

You will notice your cursor changes to a circular brush shape. Now you are ready to start painting your selection.

Understanding the Two Modes: Selection and Mask

The Selection Brush Tool offers two ways to work, and understanding both will make your editing much easier.

Selection Mode

In Selection mode, everywhere you paint becomes selected. You will see the familiar "marching ants" appear around the areas you brush over. This is ideal when you want to select a specific object or person.

Mask Mode

In Mask mode, the tool works in reverse. Areas you paint become protected from selection, shown as a coloured overlay (usually red). Everything you do not paint becomes selected. This is helpful when it is easier to paint over a background than carefully trace around your subject.

To switch between these modes:

  1. 1With the Selection Brush Tool active, look at the Tool Options bar along the bottom of the screen.
  1. 1Find the Mode dropdown menu.
  1. 1Choose either Selection or Mask depending on your approach.

Painting Your Selection Step by Step

Let us say you want to select your grandchild's face to brighten just that area. Here is exactly how to do it in Photoshop Elements:

  1. 1With your photo open in Advanced mode, select the Selection Brush Tool from the toolbox.
  1. 1In the Tool Options bar, set the Mode to Selection.
  1. 1Adjust the Size slider to match your subject. For a face, start with a medium brush — around 50–100 pixels works well for most photos.
  1. 1Set Hardness to around 50–75%. A softer edge creates a more natural selection, while a harder edge gives you precise boundaries.
  1. 1Zoom in using View → Zoom In or the Zoom Tool so you can see the details clearly.
  1. 1Begin painting over the face. Hold down your mouse button and brush carefully. The marching ants appear around your painted area.
  1. 1If you accidentally paint outside your intended area, hold down the Alt key (Windows) or Option key (Mac) while painting to subtract from your selection.
  1. 1Continue painting until the entire face is selected.

Fine-Tuning Your Selection

Once you have a rough selection, you can refine it for better results.

  • Reduce brush size for tight corners and detailed edges. Use the Size slider or press the left bracket key [ to shrink the brush.
  • Increase brush size for larger open areas. Press the right bracket key ] to enlarge the brush.
  • Switch to Mask mode temporarily to see a clear overlay of what is and is not selected. This visual check helps you spot missed areas.
  • Adjust Hardness to soften edges where hair or fur meets the background — a lower hardness creates a more natural transition.

Practical Uses for Family Photos

The Selection Brush Tool in PSE excels at tasks that matter to family photographers:

  • Brightening a face in a backlit photo by selecting just the face, then using Enhance → Adjust Lighting → Shadows/Highlights
  • Adjusting colour on clothing without affecting skin tones
  • Selecting a pet on a textured rug where automatic tools get confused
  • Isolating handwritten text in an old letter or card to enhance readability

Because you control every brushstroke, Photoshop Elements gives you the precision that family memories deserve.

Tips for Better Results

  • Work zoomed in at 100% or higher for edges that matter
  • Take your time — rushing leads to sloppy selections
  • Save complex selections by choosing Select → Save Selection so you can reload them later
  • Combine tools — start with the Quick Selection Tool for rough work, then refine edges with the Selection Brush Tool
