Generating Previews for Images Based on Rating
Another way to use previews is to create a search that displays only low-rated images.
You can then build previews just for those images, and take their master files offline
(for example, burn them to a DVD). That way you still have good-quality images for all
of your photos, without using a lot of disk space.
You can also create a search that displays only highly rated images, and then build
previews for those images only. This is a useful alternative for workflows where the
default thumbnail resolution is sufficient for low-rated images.
Generating Previews for New or Active Projects
Because previews are used by the iLife and iWork media browsers, as well as by the
Mac OS X screen saver, you can use previews as a way to distribute your Aperture
pictures in movies, on the web, on DVDs, in slideshows, and in podcasts. You can also
download your Aperture pictures to your iPod, import them into iPhoto, or use them to
create Pages documents.
To share previews with other applications:
1 Select the project whose images you want to share with other applications, then
choose Maintain Previews for Project from the Project Action pop-up menu (with a
gear icon).
2 Make sure the “Share previews with iLife and iWork” checkbox is selected in Aperture
preferences (Choose Aperture > Preferences).
3 In the Projects panel, Control-click the project and choose Update Previews for Project
from the shortcut menu.
When the previews are built, you can open any of the iLife and iWork applications and
use your Aperture images.
Generating Previews for Smart Albums
You can also create previews for images collected in Smart Albums. For example, you
can create previews for highly rated images only.
To generate previews for Smart Albums:
1 Create a Smart Album and specify criteria for it using the Smart Album’s Query HUD.
2 Click in the Browser, then press Command-A to select all the images.
3 Control-click one of the selected images and choose Update Previews from the
shortcut menu.
When the previews are built, you can share them with iLife and iWork, or drag them to
other applications.
