Sample workflows for using previews effectively

There are several methods for using preview images efficiently and effectively:

Use previews for offline referenced images

  1. Make sure the external hard disk containing the referenced originals you want to keep offline is connected to your computer.

    If the originals you want to keep offline are currently stored on your computer, you must convert the images to referenced images and move the originals to an external hard disk. You can do this by selecting the project containing the photos whose originals you want to keep offline, choosing File > Relocate Originals, selecting an external hard disk location for the originals, and then clicking Relocate Originals.

  2. Select the project containing the photos whose originals you want to keep offline, then choose Photos > Update Previews.

  3. When the previews are built (you can check the status by choosing Window > Show Activity), you can disconnect the hard disk containing the originals.

Even though the originals are offline, you can browse, search, and assign metadata to preview images. You can even use the Loupe to zoom in on preview images, because they are high-quality JPEG files.

Share previews with other applications

  1. Select the project whose photos you want to share with other applications, then choose Maintain Previews For Project from the Library Action pop-up menu .

  2. Choose Aperture > Preferences, then click Previews.

  3. Choose Always or “When quitting Aperture” in the “Share XML with other applications” pop-up menu.

  4. In the Library inspector, select the project and choose Photos > Update Previews for Project.

When the previews are built, you can open any of the iLife and iWork applications and use your Aperture photos.

Generate previews for Smart Albums

  1. Create a Smart Album and specify criteria for it using the Smart Album’s Smart Settings HUD.

  2. Click in the Browser, then press Command-A to select all the photos.

  3. Choose Photos > Update Previews.

Note:  Previews for Smart Albums are not automatically maintained—automatic preview maintenance is a project-level setting only. In this workflow, you need to update the previews yourself periodically, by following the steps in Manually manage previews. Aperture builds previews only for the versions that have changed, so you don’t need to determine which ones to update.
