Modifying preview preferences
Aperture automatically generates JPEG versions of all your images with all your adjustments
applied so that other applications, like iWork or Apple TV, can access your adjusted images.
However, these previews can take a
lot
of hard drive space if you're not careful. We cover them in
depth in Chapter 10, but for now we recommend that you either disable them entirely by dese-
lecting the New projects automatically generate previews check box or at least limiting the size to
your screen resolution and selecting a medium quality, as shown in Figure 1.21.

Running in 32-bit or 64-bit mode
One of the great new features in Snow Leopard (Mac OS X 10.6) is that it's a 64-bit operating sys-
tem, providing applications with some performance gains and allowing them to use more than
4GB of RAM at once. Aperture 3 is a 64-bit application, however, and occasionally you will need to
use an older plug-in or such that's 32-bit only. By default, Aperture automatically detects if you're
trying to use an older plug-in and automatically relaunches into 32-bit mode, but if you want to
explicitly choose whether to run Aperture in 32-bit or 64-bit mode, follow these steps:
1.
In the Finder, go to your Applications folder and select Aperture 3.
2.
Choose File
➪
Get Info.
3.
Select or deselect the Open in 32-bit mode check box depending on how you want
to run Aperture.
4.
Close the Get Info window and launch Aperture.
