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 disables automatic preview maintenance for any new projects that you create.
3 In the Projects inspector, select Library, then choose Maintain Previews For All Projects
from the Project Action pop-up menu (so there is no checkmark next to it).
This step disables automatic preview maintenance for your existing projects.
Note: You will need to perform steps 1 and 2 for each of your libraries.
4 If you have already generated previews for some projects and do not want them, select
Library in the Projects inspector, then choose Images > Delete Previews For Library.
This step deletes all previews that have previously been generated. Again, you will
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
your iPod, import them into iPhoto, or use them to create Pages documents. The media
browsers in the iLife and iWork applications now 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.
