Working with Placed Images Chapter 5, Brushes, Symbols, and Masks ). Figure 8.4. Using a clipping mask, you can display just a portion of a placed image. You can also apply color to certain kinds of placed images. Illustrator allows you to apply either a solid process or spot color to a 1-bit TIFF image, or any image that uses the grayscale color model. Simply select the image on the artboard and choose a fill color from the Swatches palette or the Color palette. Be sure to check out Conrad Chavez's example of colorizing images in the color insert. Manual Tracing with Template Layers Chapter 1, The Illustrator Environment .

In these cases, you may not actually want to trace the scan exactly as it appears (using Illustrator CS2's Live Trace feature, covered later in this chapter, might be a better choice for such a task), but rather, you just want the image to act as a reference. To prevent the image from getting in the way of your design, you might want to adjust the opacity of the image. Additionally, you may want to lock the image so that you don't move it accidentally.

Rather than going through the process of adjusting and locking images, Illustrator has a way to manage this process in a more dignified mannerusing a template layer. Once a template layer has been created, the image on that layer automatically becomes locked and the opacity level of the image is set to 50% (Figure 8.5 , left). You can either check the Template option at the bottom of the Place dialog when placing an image to have the image automatically appear on a template layer, or you can double-click any layer and check the Template option (Figure 8.5 , right).
