Where Aperture Stores Your Managed Files in the Library You always view and work with your images within Aperture. However, you may wonder where your managed image files physically reside in the Aperture library on the computer's hard disk. By default, your images are stored in the Aperture Library file within your Pictures folder. You can open and see the contents of the Aperture Library file in the Finder by Control-clicking the file and choosing Show Package Contents. However, it's not recommended that you access or work with your masters in this way because it presents a risk of interfering with the Aperture library. Warning: You should always back up and work with your managed images and projects from within the Aperture application. If you move or accidentally change the files stored in the Aperture Library file, Aperture may not be able to locate your project and images later. Making a change to a managed file in the Finder, such as renaming it, creates changes that the application cannot track. Migrating Images from Previous Versions of Aperture Aperture 2 provides new RAW decoding algorithms that deliver improved RAW image quality. With improved default rendering of RAW images from supported cameras, Aperture 2 provides significantly enhanced image quality with improvements in noise reduction, sharpening, and highlights recovery. To maintain the image integrity of the existing photos in your Aperture library, Aperture 2 enables you to retain the original RAW decoding of your images from previous versions, selectively migrate images using the new Aperture 2 RAW decoding process, or create duplicate versions of each original RAW image file with Aperture 2 RAW decoding applied. Strategies for Migrating Images When you start using Aperture 2, all of your existing images continue to use the previous version's RAW decoding process, in order to preserve their appearance. Any of these images can be individually migrated to use the new Aperture 2 RAW decoding process. You can also use the Migrate Images command in the File menu to migrate selected images, projects, books, webpages and web journals, Light Table albums, albums, and Smart Albums. Migrating a large number of images can be a time-consuming process. Therefore, you may find it easier to migrate images on an as-needed basis. For example, if you have five-star selects, you may wish to initially migrate only those images. It does not affect an image to migrate it more than once; if an image already uses Aperture 2 RAW decoding, migrating it again has no effect. 144 Part I Interface and Acquisition
