right of the interface.
Choose View
➪
Show Loupe.
Press the ~/` key.
To use the Loupe tool, click in the dark area
near the bottom right and drag it over the part
of the image you want to see magnified.
Control+click on the Loupe tool and a dialog
appears, as shown in Figure 3.11, in which you
can customize the Loupe tool as follows:
Choose Focus on Cursor to change the
behavior of the Loupe tool so that
you can leave the Loupe tool in one
place and have it display whatever is
under your cursor.
Some people prefer
to use it this way so that the Loupe
doesn't block part of the image.

Use this dialog to customize the Loupe tool.
Choose a magnification from 50 per-
cent to 1600 percent.
At magnifications greater than 200 percent, choose Pixel Grid to display a grid
within the Loupe tool.
Choose Color Value to add a readout to the Loupe of the Red, Green, and Blue
channel values as well as the luminosity value of the point under the Loupe.
Select Use Centered Loupe to toggle off this option and return to the older style
Loupe that was introduced in the original version of Aperture.
The Loupe will
change shapes slightly and whatever is shown under the small circle will appear magni-
fied in the larger part of the Loupe. Some people find this more convenient, but we pre-
fer to keep Use Centered Loupe selected and use the newer Loupe.
