Let's build a tool preseta preset that remembers how you set up a particular tool. A tool preset isn't the only kind of preset, but I cover the others in the next section, "Kinds of Presets." For this example, suppose you're on a team that creates Web ads that use photos as background images, and you often need to crop images down to a standard banner size of 468 pixels wide by 60 pixels tall. To do this without a preset, you first select the crop tool. In the options bar, enter 468px for Width and 60px for Height. Finally, you drag the crop tool to set the crop rectangle and press Return or Enter to apply the crop. If your workgroup crops hundreds of images to a few banner sizes throughout the year, you sure don't want everyone to be typing the width and height over and over. That's where a preset comes in. To create a preset for the 468 x 60-pixel banner size:
To use the preset, just click the Tool Presets picker and select the preset from the list. Suppose that in addition to Web graphics, you often produce ads at 3 by 2 inches at 300 dpi. It's just as easy to create a preset for that size and resolution. Simply follow the preceding steps 1 through 4, but with one addition: Before you create the preset, also specify 300 dpi in the Resolution field (Figure 4.2). Figure 4.2. A tool preset includes all values entered on the options bar, so creating a crop tool preset now would include the Width, Height, and Resolution values currently entered.
