Whether you're making changes to a photograph or some artwork you've created yourself, you must be able to view the image clearly to make precise changes. Typically, this means zooming in on some area that doesn't look right so that you can discern the problem, and later zooming back out again to see whether the change you made looks right when the image is viewed at its regular size. To zoom in on an image and back out again, use the Zoom tool. 1. | Select the Zoom Tool
Open an image in the Editor and then click the Zoom tool in the Toolbox.
 | 2. | Choose a Zoom Amount
The Zoom tool provides many ways in which you can zoom. To view an image at a particular zoom level (such as 50%), select the correct percentage from the Zoom box on the Options bar, type a new percentage, and press Enter. You can also use the slider on the Zoom box to select a zoom amount by dragging the slider left or right.
TIP  | To zoom in and out without actually selecting the Zoom tool first, press and hold Ctrl+Spacebar and click the image to zoom in. Press and hold Alt+Spacebar and click the image to zoom out. |
| 3. | Or Click to Zoom
TIPS | When you're zooming an image in or out to any percentage, you can change the size of the image window to fit the image, up to the available workspace, by first enabling the Resize Window to Fit option on the Options bar. To allow the image window to expand below free-floating palettes that might be in the workspace, enable the Ignore Palettes option. (To temporarily hide free-floating palettes, press Tab; press Tab again to make them reappear.) To zoom all open image windows by the same amount, enable the Zoom All Windows option. This option works only if you zoom using the Zoom In or Zoom Out buttons, and not the Zoom slider. |
You can zoom by a predetermined amount toward a particular point within an image. First, click the Zoom In or Zoom Out button on the Options bar to determine the direction of the zoom. Then click the point you want to zoom in on (or away from) within the image window.
To zoom in on a particular area of an image, simply drag with the Zoom In tool to select the area you want to see up close. The selected area is enlarged to fit the size of the image window.
| 4. | Or Zoom to a Set Size
To view the image at 100% (based on roughly 72 PPI, or optimum screen resolution), click the Actual Pixels button on the Options bar. You can also double-click the Zoom tool in the Toolbox to view the image at 100%. Assuming that a user's screen resolution is the same as yours, this option displays an image in the same size it will look on somebody else's screen.
To zoom the image as large as possible to fill the workspace, click the Fit On Screen button. You can also double-click the Hand tool in the Toolbox to fit the image to the workspace, and center the image within the window.
To zoom the image to the approximate magnification it will be when you print it (based on the current image resolution), click the Print Size button.
