Managing Photo Previews
One of Aperture's great features is the ability to make multiple adjustments and versions of your
images without actually modifying your files on disk. Unfortunately, sometimes you want to
quickly access your modified images, such as to sync to your iPhone, to set as your desktop back-
ground, or to include in an iDVD project, without having to export versions of your images.
Aperture can automatically create JPEG previews of your images, with all your adjustments, that
you can use whenever you see the media browser, such as in iWork, or even drag right from
Aperture and drop onto another application.
However, it's important to pay close attention to how you set your preview preferences so that
you don't slow down Aperture or waste tons of disk space on unneeded previews. If you're auto-
matically generating previews, Aperture updates your preview every time you make a change to
an image, which can slow Aperture down.
We keep our Aperture libraries on external drives but sync our photos to our iPhones.
To avoid photos suddenly disappearing if we sync when our drives aren't plugged
in, we use iPhoto's Aperture importer (which uses Aperture previews) to create
albums in iPhoto with our Aperture-managed images that we then sync to our
iPhones. Because our iPhoto libraries are empty (aside from these Aperture images)
and live on our main hard drives, they're always available when we sync our devices.

Controlling preview preferences
We recommend setting your preview preferences as soon as possible so that you get Aperture
creating previews the way you want right away. Start by opening the Previews preferences pane
(Aperture
Preferences and click Previews), as shown in Figure 10.2. There are a number of
options to set here.
New projects automatically generate previews. If selected, Aperture starts creating
preview JPEGs for your images as soon as you start importing images into a project. We
recommend deselecting this so that Aperture doesn't waste time creating previews for
images that you throw away. After all, how often do you keep and use every image you
import? However you'll need to remember to have Aperture create previews for some of
your images as part of your workflow.
