To set the Viewer to automatically open and compare the images in stacks, do one of the following: m Choose View > Main Viewer > Stack (or press Option-T). m Choose Stack from the Viewer Mode pop-up menu in the tool strip. For more information about using stacks, see Chapter 8, "Stacking Images and Making Picks," on page 219. Viewing Images with the Loupe Aperture has a Loupe (also called the Centered Loupe) that you can position over a portion of the image you want to magnify. You can also position the Loupe off to the side of the image and have the Loupe magnify the image at the position of the pointer. Then, as you move the pointer, you see specific parts of the image magnified. The Loupe is useful for examining the effects of adjustments as you make them, as well as making quick checks for sensor dust, flaws, fingerprints on film scans, or other issues. You can use the Loupe on any image or thumbnail in the Aperture library. Aperture also provides a second version of the Loupe for your convenience. For more information about using this alternate Loupe, see "Using the Alternate Loupe" on page 189. Chapter 6 Displaying Images in the Viewer 185
