58. Magnify Your Work
55 Zoom In and Out with the Zoom Tool
55 Zoom In and Out with the Navigator Palette
Some changes you'll want to make to an image will involve working in a small confined area. For example, perhaps you want to remove a small mole or other distraction from a person's face. To do that, you can use the Clone Stamp tool, but what if you can't see the area you want to fix all that clearly? You could zoom in, of course, but it might be nice to be able to view the changes as you make them using a more zoomed-out view. Of course, there's always the Navigator palette and its small image thumbnail, but your tiny changes might not be noticeable in that window. What you need is the ability to quickly zoom in on your work while still maintaining the big-picture view of your changes. To accomplish this task, you use a duplicate image window.
Open a Second Window
Open an image in the Editor and increase the zoom so that the area you want to work on is magnified and easy to see. To open a second window that displays the same image, choose View, New Window for XXX, where XXX is the name of the image file.
Arrange the Two Windows
Click the Automatically Tile Windows button (the four-tiny-squares button at the right end of the Shortcuts bar) or choose Window, Images, Tile from the menu to arrange the two windows on top of the other. Drag the border of the first window so that you can see the area you want to work on comfortably. Then drag the border of the second window that it doesn't take up too much room in the workspace (the second window will be smaller). You can use the first window as the work window, and the second, smaller window as a magnifier window.
If you don't want to open a second window on an image, you can quickly zoom in and out of an already open image window by pressing Ctrl+Spacebar and clicking the image window to zoom in, or pressing Alt+Spacebar and clicking the image window to zoom back out.
Change the Zoom
Change the zoom level of the second window so that the entire image fits within its boundaries: click the second image window to make it active, click the Zoom tool, and use the Option bar to adjust the zoom. You should now have two windows: one window that's larger and zoomed in on the portion of the image you want to work on, and a second window that's fairly small, which depicts the image in its entirety.
To create a larger working area, hide the Palette Bin and the Photo Bin temporarily by clicking their buttons on the Status bar.
To save time, instead of resizing the second (smaller) window and then zooming it, click the window, click the Zoom tool, and on the Options bar, enable the Resize Window to Fit option. Then drag the window to the exact small size you need.
Here, I was working on an old photo of my mother and grandmother. Like most old photos, it had some spots and scratches that needed repair. So, I zoomed in on my mother's face and began work with the Healing Brush tool. To make sure that the changes I made to her face were subtle, I opened a second window so that I could view the photograph in its entirety as I worked.
