Viewing Images with the Loupe
Aperture has a Loupe tool (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 portion of 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 checking an image’s focus, as well as making quick
checks for sensor dust, flaws, fingerprints on film scans, and 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.
