I What Are Versions? Once you have masters on your hard disk, you can review and make adjustments to your images. For example, you can change the exposure, contrast, or saturation, or add information to an image, such as the photographer's name, event, and location. To work with images, Aperture creates a "version" of each master that includes your adjustments and embedded information, and leaves the master unchanged. A version refers to the master on your hard disk, but it is not the master itself. Versions store only the thumbnail image, adjustments, and embedded information. A full image file is not created until you are ready to print or export, saving valuable storage space on your hard disk. In many cases, your workflow may call for different renderings of the same image. For example, a client may request a color as well as a black-and-white version of the same head shot. You can create multiple versions of the same image in Aperture at any time.

As you make adjustments or add information to the image, Aperture displays the image with your changes to the version, but the original master is never changed.
