Use the alternate Loupe
By default, Aperture displays the Centered Loupe when you show the Loupe to examine parts
of a photo, but you can also use an alternate Loupe. You position the small ring of the alternate
Loupe over the portion of the photo you want to see, and the large ring shows a magnified
view. Depending on the details in the photo, you can change the size of the alternate Loupe and
increase or decrease its magnification level. It’s useful for making quick checks for dust specks,
flaws, fingerprints, or other issues. You can use the alternate Loupe on any photo or thumbnail in
the Aperture library.
The alternate Loupe
shows a magnified view
of whatever is beneath it.
