Showing and Hiding Panels

Panels give you easy access to many task-specific commands and operations from color control to vector path information. By default, the main panel display is located along the right side of your window. You can use the Window menu or click a panel tab within a group to display it, and then select options on the panel or choose panel-specific commands from the Panel Options menu to perform actions. Instead of continually moving, resizing, or opening and closing windows, you can use the header bar with the panel tabs to collapse or expand individual panels within a window to save space.

The movable panels are organized into groups, such as Color/Swatches, to save screen space and help with workflow. You can also add or subtract specific panels within a group to customize your workspace. A panel appears with a header, which includes the tab titles and three options: the Collapse to Icons button, the Close button, and an Options menu. The Options menu provides you with panel commands. You can also right-click a panel title for additional options. The entire set of panels includes a double arrow at the top you can use to collapse and expand the entire panel back and forth between icons and full panels.

Working with Photoshop Tools The Photoshop toolbox contains the tools needed to work through any Photoshop job, but it's not necessary to click on a tool to access it. Simply using a letter of the alphabet can access all of Photoshop's tools. For example, pressing the V key switches to the Move tool, and pressing the W key switches to the Magic Wand tool. In addition, if a button has more than one tool available, such as the Gradient and Paint Bucket buttons, pressing the Shift key along with the tool's shortcut lets you cycle through the tool's other options. You can quickly move between tools using Spring-loaded keys. Rather than go back to the tool box when you want to switch tools, just hold down the shortcut letter key for the new tool, use the tool, and then let go of the shortcut key and you'll be back using the first tool.

Photoshop has an abundance of tools that give a Photoshop designer tremendous con- trol over any creative designing problems that may crop up. For example, the Photoshop tool box contains 11selection tools (you can never have enough selection tools), 13 painting or shape tools, 4 type tools, and 14 tools dedicated to restoring and retouching images. Add to that collection, slicing, sampling, and viewing tools and you have almost 70 tools. When you work on a document, it's important to know what tools are available, and how they can help in achieving your design goals. Photoshop likes to save space, so it consolidates similar tools under one button. To access multiple tools, click and hold on any toolbox button that contains a small black triangle, located in the lower right corner of the tool button. Take a moment to explore the Photoshop tool box and get to know the tools.

tool options include Size, Mode, Opacity, and Tolerance. The important thing to remember is that the Options bar is customized based on the tool you have selected.

You can refer to Adobe Photoshop CC Keyboard Shortcuts (available for down load on the web at www.perspection.com) for more information on all the letter assignments for the various tools. It helps to use both hands. Use one hand for your mouse or drawing tablet, and the other on the keyboard to make quick changes of tools and options.

To quickly set options on the Options bar and panels, you can use scrubby sliders. When you point to a text label of a numeric setting (cursor changes to a finger with a double arrow), and then drag left or right, the setting adjusts down or up. If you press Alt (Win) or Option (Mac) while scrubbing, values change more slowly; if you press Shift, values change more quickly. If an option doesn't have a text label, press Ctrl (Win) or ~ (Mac) while you drag over the setting.

Using the Options Bar The Options bar displays the options for the currently selected tool. If you are working with the Shape Marquee tools, your options include Feather, Style, Width, and Height. When working with the Brush tools, available

Creating a New Document

Creating a new Photoshop document requires more thought than creating a new word processing document. For example, there are resolution and color mode considerations to keep in mind. You can create as many new documents as you need for your current project. However, since operrinq more than one document takes more processing power, it's probably best to work on only one new document at a time. Once a new document is created, you have access to all of Photoshop's design and manipulation tools to create anything you can imagine.

Chapter 1

For Your Information Knowing Your Purpose and Audience Before you create an image, you need to identify the purpose of the image and the needs of your audience. The key here is communicating with your audience or client and peers about the design purpose and plans before you get started, so you don't have to re-do the image again later. The main uses for images are online, print, mobile, and video. During the planning process, you need to determine the size, resolution, color mode, background, color profile, and pixel aspect ratio you need for the type of image you want. For online, you need 72 ppi for resolution, RGB for color mode, Working RGB for color profile, and Square Pixels for pixel aspect ratio. For print, you need 300 ppi for resolution and CMYK for color mode; check with your commercial printer for other settings. For video and mobile, settings vary, so use the appropriate presets; they are a great place to start. See page 14, "Creating New Documents Using Presets," for specific instructions.


Selecting Color Modes and Resolution Selecting a Color Mode A color mode, also known as color space, determines how Photoshop displays and prints an image. You choose a different color mode (based on models used in publishing) for different tasks. You can choose a color mode when you create a new document or change a color mode for an existing document. The common color modes include: Grayscale. Best for printing black-and-white and duotone images. This mode uses one channel and has a maximum of 256 shades of gray. RGB (Red, Green, and Blue). Best for online and multimedia color images. Red, green, and blue are also the primary colors on a monitor. CMYK (Cyan, Magenta, Yellow, and Black). Best for commercial printing of color images. LAB (Luminosity, A and B channels). Best for performing image correction. This mode puts all grayscale information on the L channel and splits the colors to the A and B channels. For more information on color, see Chapter 8, "Understanding Colors and Channels."

Selecting Image Resolution Photoshop works primarily with raster documents. Raster documents are images composed of pixels.A pixel is a unit of information that holds the color and detail information of the image. Think of a Photoshop document as a brick wall, with the individual bricks in the wall representing the individual pixels in the image. Documents opened in Photoshop have a specific resolution. The resolution of the image, along with its width and height, represents how many pixels the image contains. Since pixels (the bricks in the wall) represent information, the

more pixels a document contains, the more information Photoshop has to manipulate or enhance the image. A typical 17-inch monitor displays pixels at a resolution of 1,024 x 768 pixels per inch. You can figure out how many pixels are present on a 17-inch monitor by multiplying 1,024 x 768, which equals 786,432 pixels on the screen. The resolution is equal to how many pixels fit into each monitor inch, otherwise known as ppi (pixels per inch). A typical monitor displays pixels at 72 pixels per inch. To determine the size of an image in inches, we divide the pixels by the ppi. For example, an image 1,024 pixels wide at 72 ppi would be 14.2 inches wide (1,024172 = 14.2). To determine the pixels present in an image, you multiple the size by the ppi. For example, a 3 inch image at 72 ppi would have a total of 216 pixels (3 x 72 = 216). As the image resolution drops, so does the output quality of the image. Pixelization occurs when the resolution is so low that the edges of the pixel begin to appear. The higher the resolution (more plxels), the sharper your image will be. However, the higher the resolution, the larger the file size will become. To optimize your image file size, you need to use the correct resolution for the specific task. Use 72 ppi for web pages, CD/DVDs, and multimedia; use 150 ppi for inkjet printers, 200 ppi for photo printers, and 300 ppi for commercial printing. When working with images, it's always a good idea to start with a larger image size. You can always reduce the size of the image (subtract pixels) without losing any quality. If you need to enlarge an image, you run the risk of losing image quality. When you enlarge an image, the number of pixels doesn't increase as the image does, so the pixels become larger, which results in a rougher, or more pixelated, image.

Creating a New Document Using Presets

When you create documents for specific purposes, such as, web, film, video, or for use on a mobile device, you know the importance of creating documents that will perfectly match the output requirements of the intended file destination. The preset file sizes available in the Preset menu let·you create images at a size and pixel aspect ratio that compensate for scaling when you incorporate them into various output modes. When you work with the Preset menu, the guesswork involved in creating compatible photo, web, mobile device, film and video documents in Photoshop is a thing of the past.
