2 Choose Filter > Brush Strokes > Sprayed
Strokes. Click OK to accept the default settings.
The Sprayed Strokes filter adds brush strokes to
the background.
3 Choose Filter > Artistic > Rough Pastels to
make the background look as if it were drawn with
pastel chalks. Click OK to accept the default
settings.
4 Choose Image > Adjust > Hue/Saturation
to adjust the color of the background. Drag
the sliders to change the hue (we used +92),
saturation (we used +13), and lightness (we
used – 42). Click OK.
Painting
The painting tools in Photoshop let you add color
to your artwork using preset swatches or colors
you create. Next, you’ll paint part of the image
using the paintbrush tool, and add colored type.
You’ll begin by zooming in on the frame with the
Navigator palette.
1 Choose Window > Show Navigator. The Navi-gator
palette lets you specify which part of the
image to magnify, and gives you precise control
over the magnification level, making it easier to
select small areas.
2 Drag the zoom slider in the Navigator palette to
the right to about 200%. Then drag the red rect-angle
in the preview box over the frame image.
Continue dragging the zoom slider until the frame
image fills the Tour1.psd window.
Next you’ll create a new layer to paint on.
3 Click Layer 1 (the frame layer) in the Layers
palette to make it the active layer. Hold Option
(Macintosh) or Alt (Windows) and click the new
layer icon on the palette. Holding Option/Alt lets
you name the new layer you create.
4 Enter Paint in the Name text box and click OK.
A new, active layer named Paint is added above
Layer 1.

A Quick Tour of Adobe Photoshop
5 Choose Window > Show Swatches to select a
paint color from an existing swatch. Click a color
in the Swatches palette. This sets it as the fore-ground
color—the color you’ll paint with. Notice
that the foreground color appears in a swatch near
the bottom of the toolbox, along with a swatch
representing the background color, which is used
when you erase part of an image.
6 Select the paintbrush tool (g). Then choose
Windows > Show Brushes and click a small brush
in the Brushes palette.
7 Click the Options tab and select the Wet Edges
option. The Wet Edges option gives a watercolor
effect, by building up the paint along the edges of
the brush stroke. Drag the opacity slider to the left
to make the paint slightly transparent.
8 Drag the paintbrush tool to paint over the hand.
9 Double-click the zoom tool ({) to return to
100% magnification.
You can also apply a gradient fill to create a blend
between two or more colors.
10 Select the rectangle selection tool (0). Drag
a small selection marquee from the top right of
the image.
11 Select the gradient tool (G). Click a gold
swatch in the Swatches palette to select the fore-ground
color. Then choose Foreground to Trans-parent
from the Gradient menu on the Gradient
Tool Options palette.

12 Drag the gradient tool from the top to the
bottom of the selection to set the beginning and
end of the gradient. Choose Select > None to
deselect the gradient.
Now you’re ready to create and manipulate some
type. You can modify type as you would any other
image in Photoshop. In this part of the lesson,
you’ll begin by selecting a color for the type.
13 Click a cream-colored swatch in the Swatches
palette to select the type’s color. Select the type tool
(T); then click the image.
14 Enter “PORT” in the large text box at the
bottom of the Type Tool dialog box. Choose a font
from the Font menu, enter a point size in the Size
text box, and click OK. (We used 22-point Lucida
Sans bold font.) The type is automatically placed
on a new layer.
15 Choose Layer > Transform > Rotate 90° CW to
rotate the text. Select the move tool ( ) and drag
the text on top of the gradient you just created.
16 Click in the eye column next to the X layer in
the Layers palette to add a hand drawn “X” to the
type logo.
Retouching
Adobe Photoshop provides a full range of tools for
retouching images, including dodge and burn
tools, as well as features for adjusting color, con-trast,
hue, and saturation. Next, you’ll do some
basic color correction and editing on an image.
Note: You can gain even more control over the tonal
range with the Curves dialog box. This dialog box
contains options similar to those on high-end color-correction
systems. For information on how to set
curves, see Chapter 6, “Making Color and Tonal
Adjustments.”
1 Click the Plate layer in the Layers palette to
make it the active layer.
2 To set the basic contrast and tonal range
between the highlights and shadows in the Plate
image, choose Image > Adjust > Auto Levels.
CHAPTER 1 12
A Quick Tour of Adobe Photoshop
The midtones in the plate need to be more red. To
correct them, you’ll adjust the mixture of colors in
the image with the Color Balance command.
3 Choose Image > Adjust > Color Balance. Select
the Preview option, drag the top slider toward Red,
and click OK.
Next you’ll remove a chip on the plate with the
rubber stamp tool. This tool lets you sample part
of an image and then paint with a copy of the sam-pled
area.
4 Select the rubber stamp tool (R). Click the
Brushes tab on the Rubber Stamp Options palette
and choose a medium-sized brush.
5 Place the rubber stamp tool over the plate next
to the chip. Hold down Option (Macintosh) or Alt
(Windows), and click to sample this area. Release
Option/Alt. Then drag the rubber stamp tool to
paint over the chip.
Masks
Next you'll work with a mask. A mask covers the
image, so that only the unmasked part shows
through and is affected by any changes you apply.
Adobe Photoshop provides several ways of creat-
ing and working with masks. In this part of the
tour, you'll work with a layer mask, which affects
only the image on the same layer as the mask.
1 Click the Plate layer on the Layers palette. Click
the Mask icon (q) to add a layer mask to the Plate
layer. Notice that you can see the plate through the
unmasked area.
You can modify the mask by painting on it. Black
paint adds to the mask, hiding the plate; white
paint removes from the mask, revealing the plate.
2 Select the eraser tool (e). Then drag the tool to
erase to the black background color, masking the
plate.
3 Double-click the paintbrush tool (g). Choose
Reset Tool from the menu on the Paintbrush Tool
options palette. Then drag the paintbrush tool to
paint with the white foreground color, unmasking
the plate.
Next you’ll apply a gradient to the layer mask,
creating a mask that ranges from opaque to
transparent.
4 Double-click the gradient tool (G) in the
toolbox. Then choose Foreground to Background
from the Gradient menu in the Gradient Tool
Options palette.
5 Drag the gradient tool across the plate. Where
the gradient is darker, the layer mask is more
opaque and hides the plate; where the gradient is
lighter, the layer mask is more transparent and
exposes the plate.
Resulting image
Now you’ll use the teapot on one layer as a mask
for the texture on the layer above it. Layers con-nected
in this way are called a clipping group.
6 Click the Teapot layer in the Layers palette so
you can view the layer. Then click the Texture layer
so you can view and make it the active layer.
7 Choose Layer > Group with Previous to turn the
layers into a clipping group.
The solid line separating the layers on the Layers
palette changes to a dotted line, indicating the lay-ers
are now linked as a clipping group. The texture
is now clipped to the teapot.
You can apply blending modes and opacity to clip-ping
groups the same as with layers, but the modes
will apply only within the clipping group. That is,
the modes will have no effect on any of the layers
below the clipping group.
CHAPTER 1 14
A Quick Tour of Adobe Photoshop
8 Choose Overlay from the mode menu on the
Layers palette. This mode lets the highlights and
shadows on the teapot image show through the
texture, making the texture more realistic.
You’ve added all the elements to the artwork. At
this point, you're ready to save the file.
9 Choose File > Save As. Select a folder in which
to save the file, enter a new filename, and click
Save.
You can save files in a variety of formats, depend-ing
on how you plan to use the file. For example,
you could save a file in GIF format to place the
image on the World Wide Web. (To save in most
formats other than Photoshop format, you need to
flatten the file into a single layer, as described in
chapter 11, “Using Layers.”)
Congratulations, you’ve finished the tour! Go
ahead and experiment by creating your own
Photoshop artwork as described in the following
chapters, or try some of the lessons contained on
the Tutorial CD.
