Turning Previews Off
If your workflow does not benefit from previews, you can turn them off completely.
To turn off previews
1 Choose Aperture > Preferences, then click Previews.
2 Deselect the “New projects automatically generate previews” checkbox.
This step turns off automatic preview maintenance for any new projects that you create.
3 In the Library inspector, select all the projects, then choose Maintain Previews For Projects
from the Library Action pop-up menu (with a gear icon), so there is no checkmark next
to it.
This step turns off automatic preview maintenance for your existing projects.
Note: You need to perform steps 1 through 3 for each of your libraries.
4 If you have already generated previews for some projects and do not want them, select
all the projects in the Library inspector, then choose Photos > Delete Previews.
This step deletes all previews that have been generated previously. Again, you need to
do this for each library in which you have already generated previews.
Dragging and Dropping
When a version has a preview built for it, you can drag the image directly from the Browser
to any application that accepts JPEG files, including the Finder, Mail, and most other
applications. If the version doesn’t have a preview, dragging and dropping is disabled
for that version (except within Aperture). If you are dragging multiple images, but only
some of them have previews, only the versions with previews are dragged out.
Integration with iLife and iWork
You can use previews 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
devices such as iPod, import your Aperture pictures into iPhoto, or use them to create
Pages documents. The Media Browsers in the iLife and iWork applications support browsing
Aperture libraries. For each version in the library, Aperture provides two JPEG files to iLife
and iWork: a 240-pixel (longest dimension) JPEG thumbnail that is shown in the Media
Browser, and the JPEG preview image (at whatever size you specified for it). If a version
has no preview, the image is not made available to the Media Browser.
Note: When images are within stacks, only stack picks and album picks are shared. If you
want iLife to have access to an image in a stack and it’s not the pick, you need to extract
it from the stack or make it the pick.
Integration with Mac OS X Desktop and Screen Saver System Preferences
Like images in iPhoto libraries, images in Aperture libraries can be used for your screen
saver, desktop picture, and Mail, through the same mechanism the Media Browser uses.
