Editing with Paintbrush Tools
IN THIS CHAPTER
Using paint-brushing techniques
Using brush-style editing tools to edit photos
Customizing paintbrush settings
Painting with brush and non-brush tools
Applying painting and tracing techniques
Although Photoshop is typically thought of as a photo-editing package, it also includes an
arsenal of tools that makes it one of the premier painting applications In fact, the word
“painting” in Photoshop means much more than it does in most other painting applications
What makes painting so effective in Photoshop is that Adobe combined the powerful photo-editing tools with the paintbrush tools so that you can use paintbrush strokes to apply localized photo edit-ing and you can apply photo-editedit-ing techniques to your paintedit-ing
This chapter discusses the Brush tools available in Photoshop for both editing and painting purposes
It also covers how to configure custom brushes to increase the capability of those tools Before you begin painting in Photoshop, you likely want to switch to the Painting workspace by choosing
Window ➪ Workspaces ➪ Painting from the main menu bar This configures the workspace specifically
to support the painting tools
Painting in Photoshop
Painting in Photoshop means much more than just painting colors onto a blank document with a
brush Painting means using brushing techniques to apply effects to fix problem areas of
photo-graphs, retrace history, blend layers, and apply and mix colors
In this chapter, we discuss the tools and techniques that you can use to apply some specific changes
to images, create artwork, and create dramatic artistic effects Before we start, though, you should know a few things about painting:

n Brushing techniques are applied by selecting the tool, setting the brush and tool options, and then dragging the cursor on a specific area of the document using a mouse or stylus pen
n Painting is applied to the currently selected layer in the Layers panel, although some
of the tools sample from all the layers to apply the painting effect
n When you have a selection active, the painting effect applies only inside the selec-tion This allows you to use the powerful Selection tools to fine-tune your painting
n Painting is a destructive task that alters pixels It is a good idea to paint from a copy
of the background layer if you are altering a photo and then to apply the change only when you feel that the painting is finished
n You can paint on vector layers, but you need to convert them to Smart Object layers first
n Painting is not an exact science You may need to try different brush styles, sizes, settings, and strokes to achieve the results you are looking for
Understanding the Painting Tools
The best way to understand painting in Photoshop is to look at the brush-based tools that Photoshop provides Understanding how these painting tools work can make you more effec-tive at both editing photos and applying artistic effects This section discusses the painting tools and how to use them
You use three types of paintbrush style tools to paint in Photoshop: editing, painting, and mixing Editing tools paint by adjusting the pixels directly beneath the tool Painting tools paint by applying color to the pixels directly beneath the tool Mixing tools paint by mixing color with the pixels directly beneath the tool
Tip
When you are using any of the painting tools, keep in mind that pressing and holding the Shift key while dragging the cursor results in applying the stroke in a straight horizontal, vertical, or diagonal line You can also press and hold the Shift key as you click the painting tool in two different locations in the image to create a straight paint stroke between the two points
Many of the painting tools in Photoshop are designed to take advantage of the benefits of using tablet devices Tablet devices provide a stylus and pad that work in tandem to simulate the experience of drawing with a pencil or other medium The tablet is able to sense the direction, speed, pressure, tilt, and so on of the stylus This information is transferred to the Photoshop tools where they are able to apply that information as intelligent brush strokes The results can be amazing when compared with simply using a mouse If you are planning to use the painting tools, you should seriously consider adding a tablet to your equipment

Working with painting tools in blending modes
Many of the painting tools provide blending modes that define the behavior and look of the
effect, and how it blends to the pixels beneath Blending modes are computer algorithms that define methods to combine two pixels into one pixel The idea is that instead of using one
pixel or the other, you can define several ways to combine the two pixels to create a different outcome
As you begin using the painting tools, you’ll notice that many of the tools offer a blending
mode setting of some sort The painting tools use blending modes for a variety of purposes
For example, the Brush tool allows you to set a blending mode that defines how the paint
from the brush interacts and blends with the pixels below And when adding a texture to a
brush, a blending mode is used to define how the pixels from the pattern blend with the paint
in the brush to create the texture
The following sections describe the different blending modes and how they relate to the
painting tools For the sake of the descriptions, we refer to the pixels below the brush as the
base pixels
Choosing a basic blending mode option
In Photoshop, there are four basic blending modes that enable you to edit or paint a graphic:
n Normal This is the default option for most of the Brush tools No blending is applied;
instead, the value of the new pixels is the value created by the paintbrush When painting tools use the Normal mode, the foreground color that is applied is based on the opacity, flow, and airbrush settings When editing tools use the Normal mode, the tool manipulation is applied using the normal editing algorithm
n Dissolve The blend is applied by randomly replacing the pixels with either the
paint-brush value or the pixels beneath, depending on the pixel location and the opacity setting Using this option allows you to dissipate the effect of the painting effect, more than just changing the opacity
n Behind The painting effect is applied only on the transparent areas of the layer This
mode works only when you deselect the Lock Transparency option for the layer
n Clear This applies the painting effect as transparency It’s similar to the Eraser tool,
but it works with the Shape, Paint Bucket, Brush, and Pencil tools to apply the trans-parency This mode works only when you deselect the Lock Transparency option for the layer
NoTe
The Behind and Clear blending modes are not available if the selected layer in the Layers panel is locked

tip
We created a jagged selection along the edge of the box as well as a selection around the face to take away the sharp
edge that should have been sunk slightly into the carpet
Note
You can, of course, select the areas that you want to be shown rather than the areas to be masked Then there is no
need to invert the selection
7 Click Refine Edge in the Options bar.
8 Adjust the settings to refine the edge of your selection.
9 Choose Output to Layer Mask and click OK to close the Refine Edge dialog box.
10 Drag the mask from the Image layer to the Box layer.
11 Click the eye icon to restore the Box layer to view.
Your box is masked into the photo
12 Choose File ➪ Place, browse to the file of the moon, and click OK.
13 Size the moon to fit in the box, and click the check mark to accept placement.
14 Drag the Moon layer to the top of the Layers panel, placing it on top of the box.
15 Set the moon inside the box.
16 With the Moon layer highlighted, click the Rectangular Marquee Selection tool
and create a selection that includes everything in the Moon layer that is above the box, as shown in Figure 24.31.

17 Click the Mask icon in the Layers panel to create a mask from the selection.
The moon is placed into the box Your finished product should look like Figure 24.32

You can see that even the most rudimentary 3D objects can become very interesting by using Photoshop tools to enhance them Just imagine what you can do with more elaborate 3D models

Summary
In this chapter, you learned some of the advanced techniques for working with 3D objects, how to use the Photoshop tools to change them, and how to successfully add them to com-posite images You learned how to do the following:
n Use the 3D paint tools to paint textures directly onto a 3D object
n Use adjustment layers, layer styles, and filters on a 3D object
n Create composites using images and 3D objects
