Chapter 1 An Overview of Aperture 13
Elements Used in Aperture
In Aperture, you use projects, albums, and folders to organize your images as you work.
Other important elements are the Library, used to manage your files, and the vault for
storing backup copies of your Library.
 Digital master files: The original image files imported from your camera, memory
card, computer, or external storage media. The digital master files are never changed,
so that the original image is preserved and can be used again.
 Versions: These are files used to display the master files, as well as store any changes
you’ve made to images (such as image adjustments or changes to metadata).
 Projects: Container files used to hold digital master files, versions, and albums. When
project files are moved, the contents are moved with them.
 Albums: Used to organize versions. You can create albums within projects or outside
of them. Types of albums include Smart Albums, Light Table albums, web gallery
albums, web journal albums, and book albums.
 Folders: Used to organize projects and albums within projects.
 Library: A database that manages your files from import to image adjustments and
final distribution. Once you import images, the Library records and tracks your digital
master files and corresponding versions. The Library also tracks projects and albums
you create to organize your images.
 Managed and referenced images: Master files stored in the Aperture Library are
called managed images because Aperture manages the location of the images in its
database. Managed images are physically located in the Aperture Library file in the
Pictures folder. You can also import images into Aperture without storing the digital
master files in the Library. Images that are not stored in the Library file are called
referenced images. Aperture links to referenced images in their current locations on
your hard disk, without placing them in the Aperture Library file.
 Vaults: A vault holds your backed-up images and is a copy of your Library.
For details about each of these elements and how you work with them in Aperture, see
the next few sections.
What Are Digital Master Files?
A digital master file is the original RAW, JPEG, TIFF, or PNG file that was imported into
Aperture from your camera, a memory card, a computer, or external storage media
such as an external hard disk drive or CD. Aperture never changes the master file, so
you always have originals to work from.
Important: Digital master files—especially RAW files—tend to be quite large. Projects
consisting of several thousand digital master files require high-capacity hard disks.
For information about importing your digital master files, see Chapter 5, “Importing
Images,” on page 55.
