ptg Panels 103 The Photoshop panels illustrated* Using the Tools panel e Tools panel, which is illustrated on pages 104–106, contains 60 tools and a handful of buttons! Believe it or not, by the end of this book, you’ll be marginally to intimately familiar with most of them. To display the Tools panel if it’s hidden, choose Window > Tools. To choose a tool, do one of the following: ➤ If the desired tool is visible on the Tools panel, click its icon. ➤ To cycle through related tools in the same slot, Alt-click/Option-click the one that’s visible. ➤ To choose a hidden tool, click and hold on the visible tool, then click a tool on the menu. ➤ To select a tool quickly, press its designated letter shortcut (don’t do this if your cursor is in type). e shortcuts are shown in the screen captures on the next three pages. e shortcut for each tool is also listed in its tool tip onscreen. If Use Shift Key for Tool Switch is unchecked in Edit/Photoshop > Preferences > General, simply press the designated letter to cycle through related tools in the same slot (for example, press L to cycle through the three Lasso tools). With the Use Shift Key for Tool Switch option checked, you have to press Shift plus the designated letter. ➤ To use (spring-load) a tool temporarily while another tool is selected, press and hold down its assigned letter key (see the sidebar at right). To learn the function of a tool as you’re using it, read the brief description (tool hint) at the bottom of the Info panel. If you don’t see the tool hint, choose Panel Options from the Info panel menu, then check Show Tool Hints (see page 114). Before using a tool that you’ve selected, you need to choose settings for it from the Options bar at the top of your screen. For example, for the Brush tool, you would choose a brush preset, and choose diameter, hardness, blending mode, opacity percentage, and other settings. If the Options bar is hidden, you can display it by choosing Window > Options (see page 100). e current Options bar settings for each tool remain in eect until you change them, reset the tool, or reset all tools. To restore the default set- tings to a tool, right-click the thumbnail on the Tool Preset picker (located at the left end of the Options bar) and choose Reset Tool from the con- text menu. A Or to reset all tools, choose Reset All Tools from the menu, then click OK in the alert dialog. In Edit/Photoshop > Preferences > Cursors, you can control whether the pointer displays as cross- hairs or as the icon of the current tool or, for some tools, as a circle either the size or half the size of the current brush diameter, with or without the crosshairs inside it (see page 392). SPRING-LOADING YOUR TOOLS ➤ To quickly access a tool and its Options bar settings temporarily without having to actually click the tool on the Tools panel, hold down its letter shortcut key. For example, say the Brush tool happens to be selected but you want to move a layer, which requires using the Move tool. You would hold down the V key, drag in the document window, then release V. Or to access the Zoom tool temporarily, you would hold down the Z key. ➤ This process is slightly less effi cient if you want to access a tool that shares a slot with other tools (as most tools do). In this case, the letter shortcut accesses whichever tool happens to be visible on the Tools panel. To make this work, you could plan ahead and select the tools that you want to switch back and forth among before using them. A To access these two commands, right-click the Tool Preset picker thumbnail, which is located at the left end of the Options bar. * e 3 D t o o l s , a n d t h e 3 D , A c t i o n s , A n i m a t i o n , M e a s u r e m e n t L o g , N o t e s , a n d P a t h s p a n e l s a r e n ’ t i l l u s t r a t e d i n t h i s c h a p t e r b e c a u s e they aren’t covered in this book. ptg 104 Chapter 6 A  e u p p e r p a r t o f t h e T o o l s p a n e l Creates rectangular selections Creates oval and circular selections Creates 1-pixel-wide horizontal selections Creates 1-pixel-wide vertical selections Selects areas that it detects within clearly dened shapes Selects pixels that are similar in color to the one that’s clicked Crops the image Slices images for optimization (for Web output) Selects slices by clicking Samples colors from an image Places color sampler (readout) points in an image Measures distances and angles or straightens the image ★ Creates Acrobat-compatible annotations Applies brush strokes Draws freehand lines Changes colors while preserving textures Simulates traditional paint strokes; allows colors to be mixed and smudged ★ Corrects aws without sampling Corrects aws based on a sampled area Corrects aws based on a selected area Corrects red-eye in portrait photos Clones imagery within or between documents Stamps patterns Click on or near this collapse/expand button to toggle the panel’s double- column and single-column formats.

GETTING INFO ON PHOTOSHOP FEATURES ➤ If you’re unsure what an icon signifi es, what a menu is called, or what a panel or dialog feature or tool does, you may get the information you need from the tool tip. Let the pointer hover on the feature in question without clicking the mouse button, and a tip pops up onscreen. (For this to work, Show Tool Tips must be checked in Edit/Photoshop > Preferences > Interface.) ➤ Some dialogs (such as Edit > Color Settings) have a Description area that contains information about the option your pointer is currently hovering over. ➤ Keep an eye on the Info panel for color breakdown readouts, document data (e.g. fi le size, color profi le, dimen- sions, resolution), and tool hints (ways to use the currently selected tool). See page 114. ➤ Use the Histogram panel to monitor changes to the tonal ranges in an image as you apply color and tonal adjustments. See pages 203–204.

Plus, adjustment layers automatically have a layer mask. By editing the mask, you can hide or reveal the adjustment eect in specic areas of the image. Using the Adjustments panel, you can easily create and edit the settings for adjustment layers. e panel also lets you restore the default settings to any adjustment; hide and show the adjustment eect; view the previous adjustment state; or, in a multi- layered document, clip (limit) the adjustment eect to just the underlying layer. See Chapters 12 and 13.

Open this panel from the Window menu, or when a type tool is selected, by clicking the Toggle Character and Paragraph Panels button on the Options bar. See Chapter 20. Channels panel e Channels panel displays a list of, and the thumbnails for, all the color channels in an image. To show an individual channel in the document window, click the channel name or press the keystroke listed on the panel. To redisplay the composite image (all the channels), such as RGB or CMYK, click the topmost channel on the panel, or press Ctrl-2/Cmd-2. (See pages 2–3.) You can also use this panel to save and load alpha channels (which are saved selections). See page 160.

You can also use this panel to hide, show, and control the opacity and mode of the clone overlay, and ip, scale, rotate, invert, or reposition the source pixels before or while you clone them.

Choose a color model for the sliders or color ramp from the panel menu, then either mix a color using the sliders or quick-select a color by clicking the color ramp. To open the Color Picker (or the Color Libraries dialog, from which you can also choose colors), click once on the Foreground or Background color square on the Color panel if it’s already selected (has a black border), or double-click the square if it’s not selected. Colors are applied by painting and editing tools, such as the Brush and Pencil tool, and by some commands, such as Edit > Fill and Image > Canvas Size. See page 188.

Via the Channel menu, you can choose to have the panel display data about the composite chan- nel (combined channels) or just a single channel. You can also expand the panel to display a separate histogram for each channel (as is shown at right). See pages 203–204.
