54. Arrange the View of Multiple Images in the Editor

As you work on an image, you might find it convenient to open a similar image at the same time. For example, perhaps you're copying data from one image into the other. Or perhaps you're trying to match the brightness or contrast levels in both images. In any case, the Editor provides commands that will help you not only arrange multiple images so that you can review them both easily, but also to zoom in on the same location within each image, such as the upper-right corner.
As you learned in 43 About the Editor, Multi-window mode enables you to arrange open images in either a tiled fashion (in which images are placed in similarly sized windows, right to left, like ceramic tiles) or in a cascade (in which images slightly overlap each other, like a deck of cards). Because the cascade arrangement does not allow you to really compare two images, you'll use the tiled arrangement in this task. After you've arranged your two images in a tiled fashion, you can zoom in at the same level and even scroll to the same location within the image windows, as explained in this task.
Open Multiple Images
In the Organizer, click the thumbnail of the first image you want to work on, then press Ctrl and click the second one. Then on the Shortcuts bar, to open the Editor and display the images, click the Edit button, and from the menu that appears, choose Go to Standard Edit.
If the Editor is already open and you are working on other image(s), minimize those image windows or save and close them (if you're done working on them) before beginning this task.
You can arrange multiple image windows only while using Standard Edit. This task does not work while you are in Quick Fix mode.
Tile the Images
If the Automatically Tile Windows button (the "four squares" icon at the right end of the Editor's menu bar) is pushed in, the two images will be automatically tiled for you. If not, click the Automatically Tile Windows button to enable it, or choose Window, Images, Tile to arrange the two images in a tiled pattern.
To zoom in both images by the same amount, click one image window to make it active. Then adjust the zoom using the Navigator palette. See 56 Zoom In and Out with the Navigator Palette for help.
Do not adjust the zoom using the Zoom tool, or the two windows might become untiled. If that happens, repeat step 2 to retile the windows.
To make more room for the two tiled windows, you might want to hide the Photo Bin by clicking its button on the Status bar.
Choose Window, Images, Match Zoom. The second image is zoomed to the same level as the active image.
Whether or not you match the zoom between the two images, you can scroll to the exact same location within each image window. To do that, click one image window to make it active. Then scroll to the portion of the window you want to see. You can use the scrollbars, the Hand tool, or the Navigator palette, as explained in 57 Scroll a Large Image.
Choose Window, Images, Match Location. The second image is scrolled to the exact same location as the first image. Here, I opened two similar images, arranged them, and then zoomed them to the same level and the same location so that I could clone the horse's head from one image into the other, essentially erasing the person on the right from the second image.
You can continue to match the locations within the two images, even as you scroll. Just click the Hand tool in the Toolbox and enable the Scroll All Windows option in the Options bar. Then click in one window and scroll using the Hand tool. The second window is scrolled by that same amount.
