Photoshop’s Brush tool looks simple: pick a color, drag across the canvas, and paint appears. But behind that single icon sit dozens of settings that decide whether your strokes look like a felt marker, a soft airbrush, or textured oil paint. Most frustration with digital painting, such as wobbly lines, strokes that will not taper, or color that builds up too fast, comes from a handful of those settings. This guide explains how to use brush tool in Photoshop, covering everything from the very first stroke to custom presets, with the shortcuts that speed everything up. The rest depends on your input device, which is why pairing these settings with a pressure-sensitive stylus built for Photoshop painting changes so much.
Quick answer: To use the Brush tool in Photoshop, press B (or click the brush icon in the toolbar), choose a foreground color, then pick a brush tip from the options bar or Brushes panel. Set size with the [ and ] keys, hardness with Shift plus [ or ], and adjust Opacity, Flow and Smoothing in the options bar. Paint on a new layer by dragging on the canvas; hold Shift to draw straight lines and Alt (Option on Mac) to sample colors. With a pressure-sensitive pen, turn on pressure for size and opacity to get tapered strokes.
Before You Paint: Set Up the Canvas and Layers
A few seconds of setup prevents the most common beginner problem, which is painting directly on a photo or background and being unable to undo specific strokes later.
- Create or open a document. For painting, a canvas at 300 pixels per inch is a common choice for print, while screen work can use lower resolution. Large canvases with big brushes demand more computer memory, so start moderate.
- Add a new layer. Click the New Layer button at the bottom of the Layers panel, or press Ctrl+Shift+N (Cmd+Shift+N on Mac). Painting on separate layers lets you erase, move and adjust parts independently.
- Check the color mode. RGB is standard for digital painting. Some filters and brush behaviors are limited in other modes.
How to Use the Brush Tool in Photoshop: Step by Step
- Select the Brush tool. Press B, or click the brush icon in the toolbar. If the Pencil, Color Replacement or Mixer Brush tool is showing instead, click and hold the icon (or press Shift+B to cycle) until you reach the Brush tool.
- Pick a foreground color. Click the top color swatch at the bottom of the toolbar to open the Color Picker, or use the Color or Swatches panels. Press D to reset to black and white, and X to swap foreground and background.
- Choose a brush tip. Click the brush preset picker in the options bar (the small brush icon with a size number). Start with a “Soft Round” or “Hard Round” from the General Brushes group.
- Set the size. Use the slider in the preset picker, or press ] to enlarge and [ to shrink.
- Set the hardness. Hard brushes have crisp edges; soft brushes fade at the edges. Use the hardness slider, or press Shift+] and Shift+[.
- Adjust Opacity and Flow in the options bar (more on these below).
- Paint. Click and drag on the canvas. Release and drag again to start a new stroke.
- Undo if needed. Ctrl+Z (Cmd+Z) undoes the last step; repeated presses step further back in recent versions of Photoshop.
The Options Bar: Settings That Change Every Stroke
When the Brush tool is active, the options bar at the top of the screen holds the controls you will adjust most.
| Setting | What it does | Typical use |
|---|---|---|
| Brush preset picker | Choose tip, size, hardness | Switching brushes quickly |
| Mode | Blend mode of the stroke itself | Usually Normal; Multiply for shading, Color for tinting |
| Opacity | Maximum transparency of a single stroke | Lower for glazing and soft buildup |
| Flow | How quickly paint is applied as you move | Lower for gradual buildup within one stroke |
| Airbrush toggle | Paint keeps building while the cursor is held still | Soft shading with a stationary brush |
| Smoothing | Stabilizes strokes to reduce jitter | Line art and lettering, often 10 to 30 percent |
| Pressure for opacity / size buttons | Let pen pressure control opacity or size | Natural tapered strokes with a stylus |
| Angle | Rotates the tip | Calligraphic and flat brushes |
| Symmetry | Mirrors strokes along a guide | Patterns, mandalas, character design |
Opacity vs Flow, explained simply
These two settings confuse many people because both make strokes lighter. The difference is about what happens inside a single stroke.
- Opacity sets a ceiling. At 50 percent opacity, a single stroke can never be more than 50 percent opaque, no matter how many times you go back and forth without lifting the pen.
- Flow sets the rate. At 20 percent flow, each pass deposits a little paint, and overlapping within the same stroke builds it up toward the opacity limit.
For smooth blending, many digital painters keep opacity at 100 percent and lower flow, or tie opacity to pen pressure. For flat, even glazes, they lower opacity instead.
Using a Pen Tablet or Stylus With the Brush Tool
A mouse can paint, but it cannot vary pressure, so every stroke has the same width and opacity. A pressure-sensitive pen tablet, pen display or compatible stylus unlocks tapered lines and natural shading. Hardware choice matters here, since devices differ in pressure levels, tilt support and palm rejection.
Once a pen is connected:
- Click the pressure for size button in the options bar (a circle with a pen icon next to the size setting) to make harder pressure produce wider strokes.
- Click the pressure for opacity button (next to the Opacity field) to make harder pressure produce darker strokes.
- For finer control, open Brush Settings and adjust Shape Dynamics and Transfer, described below.
- If pressure does not seem to work, check the tablet driver settings and the operating system’s pen settings, and restart Photoshop after installing a driver.
The Brush Settings Panel: Making Your Own Brushes
Open Window > Brush Settings (or press F5) to see the full set of brush controls. Each category on the left changes a different behavior.
Brush Tip Shape
Sets the basic tip, size, angle, roundness, hardness and spacing. Spacing is easy to overlook: at high spacing values the brush stamps visible dots; at low values it draws a continuous line. Around 10 to 25 percent gives smooth strokes for most round brushes.
Shape Dynamics
Controls how size, angle and roundness change during a stroke. Set Size Jitter’s Control to Pen Pressure for tapered lines. Minimum Diameter sets how thin the stroke gets at the lightest pressure.
Scattering
Spreads stamps around the stroke path. Useful for foliage, stars, dust and texture brushes.
Texture
Applies a pattern inside the stroke so it looks like paint on canvas or paper. Adjust Depth and Scale to control how strong the texture appears.
Dual Brush
Combines two tips, so the second tip acts as a mask on the first. Good for broken, dry-media edges.
Color Dynamics
Varies hue, saturation and brightness as you paint. Small amounts add natural variation; large amounts look random.
Transfer
Controls how opacity and flow change during the stroke. Set Opacity Jitter’s Control to Pen Pressure for pressure-based shading.
Other checkboxes
Wet Edges makes strokes darker at the edges, like watercolor. Build-up mimics airbrush buildup. Smoothing smooths curves. Protect Texture keeps the same texture across brushes.
Saving a custom brush
Once you have settings you like, open the Brushes panel menu and choose New Brush Preset. Name it and choose whether to include tool settings and color.
How to Use Brushes in Photoshop: Importing and Organizing
Photoshop includes a set of default brushes, and you can add more from Adobe or other brush makers. Brushes are typically distributed as .abr files.
- Open Window > Brushes.
- Click the panel menu (the four lines at the top right).
- Choose Import Brushes and select the .abr file. You can also double-click the file or drag it into Photoshop in many versions.
- Imported brushes appear as a new group at the bottom of the Brushes panel.
- Organize brushes into groups with the folder icon, and delete unused ones to keep the panel manageable.
Legacy brushes from older Photoshop versions can be restored through the Brushes panel menu (Legacy Brushes) if your version includes that option.

Practical Techniques With the Brush Tool
Clean line art
Use a hard round brush, size around 4 to 10 pixels at typical resolution, with pressure for size on and Smoothing between 10 and 40 percent. Draw on a dedicated layer above a rough sketch layer set to low opacity. Rotate the canvas with R so you can pull strokes in a comfortable direction.
Soft shading
Use a soft round, low flow (5 to 20 percent), and a Multiply layer for shadows or a Screen or Overlay layer for light. Build up gradually. Clipping masks keep shading inside a base shape: place the shading layer above the shape and choose Create Clipping Mask from the Layers panel menu.
Painterly blocking in
Choose a textured brush, such as a chalk or charcoal style from the default sets, and paint large shapes at high opacity. Sample colors frequently with Alt or Option to blend by picking intermediate tones.
Blending with the Mixer Brush
The Mixer Brush tool, grouped with the Brush tool, blends colors already on the canvas as you paint, much like wet media. Adjust Wet, Load and Mix in the options bar, and turn on Sample All Layers if your colors are on different layers.
Straight edges and perspective
Click once to start, then Shift+click to draw a straight line to the next point. Combine with guides or a perspective grid layer for architecture.
Troubleshooting Common Brush Tool Problems
- Nothing paints. Check that the right layer is selected, the layer is not locked, opacity and flow are not at 0, and there is no active selection elsewhere on the canvas (press Ctrl+D or Cmd+D to deselect). Also check that you are not painting on a hidden layer or inside a layer mask.
- Cursor shows a crosshair instead of the brush outline. Caps Lock is on. Turn it off.
- Strokes look dotted. Spacing is too high in Brush Tip Shape. Lower it.
- Strokes lag behind the pen. Lower Smoothing, use smaller brushes, reduce canvas size, or check GPU settings in Preferences.
- Pressure not working. Turn on the pressure buttons, set Control to Pen Pressure in Shape Dynamics and Transfer, and check tablet drivers.
- Brush paints the wrong color. Make sure Color Dynamics is not adding jitter, and that the blend mode is Normal.
FAQs
How to use brush in Photoshop for beginners?
Press B, pick a color, choose a Soft Round or Hard Round brush from the options bar, set size with the bracket keys, and paint on a new layer. Start with 100 percent opacity, then experiment with lower flow for softer buildup.
How to use brushes in Photoshop that you downloaded?
Open the Brushes panel, choose Import Brushes from the panel menu, and select the .abr file. The new brushes appear as a group at the bottom of the panel.
What is the difference between the Brush tool and the Pencil tool?
The Brush tool produces anti-aliased strokes with soft or hard edges. The Pencil tool produces hard, aliased edges with no smoothing, which suits pixel art.
Why is my brush so slow in Photoshop?
Large brush sizes, high Smoothing, complex brush settings and very large canvases all slow performance. Try smaller brushes, lower Smoothing, and enable GPU acceleration in Preferences.
Do I need a drawing tablet to use the Brush tool?
No, a mouse works, but you lose pressure sensitivity. A pen tablet or compatible stylus makes tapered lines and natural shading much easier.
How do I make a brush taper at the ends?
With a pressure-sensitive pen, turn on Shape Dynamics and set Size Jitter’s Control to Pen Pressure. Without a pen, Shape Dynamics offers a Fade control that shrinks the stroke over a set number of steps.
