Navigation

In this section, we first explore some of the fastest ways to move around your image, including zooming in and out. Then we discuss moving pixels around both within your document, and from one document to another. It's funny, but we find that even expert users forget or never learn this basic stuff, so we urge you to read this section even if you think you already know all there is to know about navigating in Photoshop. Plus, Photoshop CS snuck in a few new zoom and scroll tricks.

Magnification

Images got pixels. Computer screens got pixels. But how does one type of pixel relate to the other type of pixel? When you display an image on your screen, Photoshop has to match image pixels to screen pixels (see Figure 2-2). The percentage in the title bar of the document window tells you how Photoshop is matching up those pixels.
