Chapter 2). If the zoom ratio is 100 percent, for example, each image pixel takes up a single screen pixel. Zoom ratio and printer output are unrelated.
This same rule applies outside Photoshop as well. Other programs that display screen images — including multimedia development applications, presentation programs, and Web browsers — default to showing one image pixel for every screen pixel. This means that when you're creating an image for the screen, the Resolution value has no effect whatsoever. I've seen some very bright people recommend that screen images should be set to 72 ppi on the Mac or 96 ppi for Windows, and while there's nothing wrong with doing this, there's no benefit either. When publishing for the screen, the Resolution value is ignored.So all that counts is the 100-percent view. That means you want the image to fit inside the prospective monitor when you choose View Actual Pixels (Ctrl+Alt+0 on the PC or z -Option-0 on the Mac) inside Photoshop. I say prospective monitor because although you may use a 17-inch monitor when you create the image, you may need the final image to fit on a 13-inch display. So even though your monitor probably displays at least 1,024768 pixels, many Web and screen artists prepare for the worst-case scenario, 640480 pixels. This is the ancient 13-inch VGA standard, shared by some of the first color Macs and PCs. These days, you'd be hard-pressed to find a computer monitor capable of less than 800600 pixels.
| Caution | Of course, a 640480-pixel image would consume an entire 13-inch screen. If you want the image to share the page with text and other elements, the image needs to be smaller than that. A typical screen image varies from as small as 1616 pixels for icons and buttons to 320240 pixels for a stand-alone photograph. Naturally, these are merely guidelines. You can create images at any size you like. |
