Hands On 4: Channels


The goal of this project is to learn important techniques that enable you to make, store, and edit selections as alpha channels. You ll begin by selecting a region of an image with the manual selection tools (you ve had plenty of practice making selections in Hands On 1). Then, using Quick Mask, you ll refine the selection to a high degree of accuracy. Next, you ll save the selection as an alpha channel, duplicate it, and apply a fill that will greatly alter its capabilities. Finally, you ll apply a Photoshop filter through the new selection to give the image movement and life.

Getting Started

Discard your preferences file before beginning this Hands On exercise. The Modifying Photoshop s Settings section in Chapter 5, Setting Up Photoshop, details how to reset your preferences to Photoshop s defaults. After you have launched Photoshop with default preferences, open the file Chickens_in_Motion_start.psd in the HO4 folder on the Photoshop CS Savvy CD. Save the file to your disk. Figures H4.1 and H4.2 show the before and after images (for a color version, check Figures C46 and C48 in the color section).
