Aperture 3.x: An Overview of Importing Photos
Aperture provides tools and workflow options that make it easy to import your photos. You can import photos directly from your digital camera or card reader, and import photos stored on your computer hard disk or other storage devices. You can also import audio and video files.
You no longer have to import photos individually from your iPhoto library into Aperture. Aperture can open, view, and work with iPhoto libraries the same way it works with multiple Aperture library files. For more information about opening your iPhoto library in Aperture, see An Overview of Library Files.
When you import from a digital camera or card reader, Aperture places the photos in a project. If you don’t select an existing project, a new one is created automatically.
As Aperture imports photos, video files, and audio files, it generates a version file, preview, and thumbnail corresponding to each original.
You can import originals directly from a digital camera or card reader and from your hard disk drives.
When you import photos, you can choose whether to have the originals stored in the Aperture library or on a hard disk outside of the library, where they can be accessed as referenced images. For more information about referenced images, see What Are Managed Images and Referenced Images?.
As you import photos, you can set Aperture to automatically name and record information about them. Aperture can assign filenames using custom naming conventions; record metadata such as captions, keywords, dates, copyright and credit information, and IPTC information; and adjust the time when the photo was shot to the correct time zone. If the photo has an XMP sidecar file, Aperture imports it as well and adds the metadata to the image version. You can even set Aperture to automatically back up your photos as they are imported.
