Healing Brush, Spot Healing Brush,
Dodge, Burn, Sharpen, Clone Stamp,
and Eraser In this chapter, you will paint with
the Brush tool, choose and customize brushes using
the Brush panel, and manage brush presets using the
Brush Presets panel You will create bristle brushes for
the new Mixer Brush tool, use that tool to transform a
photo into a painting, smudge colors with the Smudge
tool, then finally zap out parts of an image with the
Eraser and Magic Eraser tools
Using the Brush tool
Before delving into the complexities of the Brush
panel, take a few minutes to get acquainted with the
Brush tool In these instructions, you’ll choose a brush
preset for the tool and choose Options bar settings to
control its behavior
To use the Brush tool:
1 Click an image layer or create a new layer
Optional: If you want to confine your brush strokes
to a specific area, create a selection
2 Choose the Brush tool (B or Shift-B)
3 Choose a Foreground color.
4 On the Options bar, do the following:
Click the Brush Preset picker arrowhead or
thumbnail, then click a preset.A
Choose a blending Mode (see pages 192–196)
Choose an Opacity percentage At 100%, the stroke
will completely cover underlying pixels
Continued on the following page
A Click the Brush Preset picker arrowhead or thumbnail on the Options bar, then double-click a preset on the picker.

Choose a Flow percentage for the rate at which
paint is applied (for thick or thin coverage)
Click the Airbrush button, if desired, to allow
the paint to spread and build up when you hold
down the mouse, as in traditional airbrushing
5 Optional: If you have a stylus and tablet, you
can activate the Tablet Pressure Controls Opacity
button and/or the Tablet Pressure Controls
Size button on the Options bar.★

SHORTCUTS FOR CHANGING TOOL SETTINGS
With the Blur, Brush, Burn, Clone Stamp, Color Replacement, Dodge, Healing Brush, Paint Bucket, Pencil, Sharpen, or Smudge tool, some or all of these shortcuts can be used:
Cycle through blending modes for the tool
Shift- + (plus) or Shift - - (minus)
Change the opacity, exposure, or strength percentage* (Shift-press a number to change the Flow level)
On the row of number keys or the keypad, press a digit between
0 and 9 (e.g., 2 = 20%) or quickly type a percentage (e.g., “38”); 0 = 100%
* If the Airbrush option is on, press a number to change
the Flow percentage or Shift-press a number to change the Opacity percentage.
C You can make a temporary change to the Size or
Hardness of a preset quickly via the context menu.

Choosing temporary brush settings
There are a gazillion ways to customize a brush
An easy way to start is by changing the Size and Hardness settings The settings will remain in effect until you choose a different preset
To choose temporary settings for a brush preset:
1 Choose any tool that uses brush presets, such as
the Brush, Mixer Brush, Pencil, or Eraser tool
2 Do one of the following:
Right-click in the document, then change the
Size and/or, if available, the Hardness value (you
can use the scrubby sliders), then press Enter/
Return.CThese settings can also be changed on the Brush Preset picker, which opens from the Options bar (see the preceding page), and the Size can also be changed via the Brush panel (see page 257) or Brush Presets panel (see page 260)
To resize the brush via the keyboard, press [ or ]
To resize the brush interactively, Alt-right-click-drag/Control-Option-drag horizontally
in the document If OpenGL was on in Edit/
Photoshop > Preferences > Performance when Photoshop was launched and a round or elliptical brush is selected, a color (representing the cur-rent hardness value) displays in the brush cursor
as it’s scaled To change the hardness, drag vertically using the same shortcut.★

Customizing a brush
Via a wealth of features on the Brush panel, you can
customize the characteristics of any brush for use
with the Brush, Mixer Brush, Smudge, or Eraser tool
(all of which are featured in this chapter), and for
the Pencil, History Brush, Art History Brush, Clone
Stamp, Pattern Stamp, Blur, Sharpen, Dodge, Burn,
and Sponge tools
On the Brush panel, most of the settings for
customizing brushes are organized into option sets;
a few solo options simply get switched on or off
Many of the options are dynamic, meaning they add
randomness or variation to the stroke, such as to its
shape, texture, or color The availability of options
varies depending on the currently chosen tool and
tip, and some features apply only to a graphics tablet
and stylus The choices are vast, but we’ll boil them
down to the ones we gravitate to With practice,
you’ll learn which options and settings suit your
painting style
To customize a brush via the Brush panel: ★
1 Choose a tool from the list at the top of this
page To see the greatest differences among the
settings, select the Brush or Mixer Brush tool
2 To show the Brush panel, click the panel tab or
icon or click the Toggle Brush Panel button
on the Options bar Click Brush Tip Shape on
the left side of the panel, and for now, click a
non-bristle tip (a tip that doesn’t look like a
drawing of a brush).A
3 As you adjust settings for the tip, keep an eye on
the stroke preview at the bottom of the panel:
To change the brush Size (diameter), use the
slider or scrubby slider (To restore the original
size to a non-Round or nonbristle preset at any
time, click the Restore Original Size button )
To change the Angle (slant) of an elliptical tip,
use the scrubby slider, or drag the arrowhead
around the circle, or enter a specific angle
To change the Roundness of the tip (make it
more oval or more circular),Buse the scrubby
slider (0–100%) or drag either of the two tiny
dark circles on the ellipse inward or outward
To change the Hardness of the tip (feather or
sharpen its edge),Cmove the slider or enter a
percentage This option isn’t available for all the
brush tips
Continued on the following page
A The Brush panel lets you choose a brush tip, customize it via a wide assortment of options, and save it as a preset The preview at the bottom of the Brush panel updates dynami-cally as you change the settings.
20% Roundness
B 100% Roundness
3% Hardness
C 100% Hardness
WHERE THE BRUSH TIPS COME FROM
When you load a library onto the Brush Presets panel (see page 260), the tips that are used by those presets also load onto the Brush panel, and display in the scroll window on that panel when you click the Brush Tip Shape button Eight or nine standard tips also display below the other tips in the scroll window
Trang 4
To control the distance between marks within
the stroke, check Spacing, then move the slider
(1–1000%),A–B or turn this option off to let the
speed of your brush stroke control the spacing
4. Next, you’ll customize the behavior variations
for the chosen brush, using three of the option
sets on the panel Checking the box for an option
set, such as Scattering, activates the current
settings for that set; clicking the set name both
activates the current settings and displays the
set options If an option set isn’t available for the
current tool, the set name is dimmed
To control the amount of allowable variation in
the brush tip shape, click Shape Dynamics, then
do any of the following:
Choose Size Jitter, C Angle Jitter, and
Roundness Jitter values to establish an
allow-able amount of random variation for those
attri-butes The variations are more noticeable when
the Spacing value (in the Brush Tip Shape option
set) is greater than 10%
➤ To have the angle of the brush tip reflect the
direction of your strokes, under Angle Jitter,
choose Control: Initial Direction
If you have a stylus, from each of the Control
menus, choose which stylus feature is to control
the variation for that option Note that
varia-tions will occur even when this setting is Off
Choose Minimum Diameter and Roundness
percentages
5. To control the placement of pigment in the
stroke, click Scattering, then do any of the
following:
Check Both Axes to scatter pigment along and
perpendicular to the stroke you draw, or uncheck
this option to scatter pigment perpendicular
to, but not along, the stroke.DAlso choose a
Control option, if desired
Choose a Scatter percentage (1–1000%) to
control how far the pigment can stray from the
stroke The lower the Scatter percentage, the
more solid the stroke
Choose a Count value (1–16) to control the
number of marks in the stroke (also increase the
Spacing value)
Choose a Count Jitter percentage (0–100%) to
control the amount of variation in the Count.E
A With Spacing checked, the spacing is uniform:
25% Spacing (top) and 150% Spacing (bottom)
B With Spacing unchecked, the spacing is uneven: A slow stroke (top) and a fast stroke (bottom)
C 0% Size Jitter 100% Size Jitter, 25% spacing
0% Scatter, 100% Spacing
500% Scatter, Both Axes option checked
D 500% Scatter, Both Axes option unchecked
0% Count Jitter, 100% Spacing
E 100% Count Jitter: The Count varies randomly from 1% to 100% of the Count value.

6 To control how randomly the overall stroke
opac-ity can vary as you use the tool, click Transfer,
then do any of the following:
Choose an Opacity Jitter percentage (0–100%)
for the amount the opacity can vary.A–DChoose
a Control option to control the fading
Choose a Flow Jitter percentage (0–100%) to
control the rate at which paint is applied A high
Flow Jitter will make the stroke blotchy, but that
may be the look you’re after Choose a Control
option
7 And last but not least (you’re almost done!),
check any of these options on or off:
Noise to add random grain to your brush strokes
to make them look more rough
Wet Edges to simulate the buildup of pigment
that occurs at the edges of brush strokes in
traditional watercoloring.E–F
Airbrush to allow strokes to build up for as long
as the mouse button is held down in one spot
Activating the Airbrush button on the Options
bar does the same thing This effect is noticeable
only when the Spacing value is greater than 6
Smoothing for smoother curves.
Protect Texture to apply the same texture
pat-tern and scale to other brushes for which the
Texture option is enabled, to create a uniform
surface texture across the entire canvas
8. Optional: Click the open lock icon next to
the name of any option set (the icon becomes a
closed lock) to prevent the current settings in
that set from being edited, even if you change
presets Locked settings are applied, but not
saved, to any other preset you choose To make
those settings editable again, click the closed
lock icon
9 Beware! The custom settings that you have
chosen are only temporary To save them as a
brush preset for future use, click the Create New
Brush button at the bottom of the Brush
panel Change the name in the Brush Name
dialog (include some settings in the name for
easy identification), check Capture Brush Size in
Preset ★ (if desired), then click OK Your saved
