Working with Photo Stream

In order to use Photo Stream, you must set up a free iCloud account. With an active iCloud account, you can enable your Aperture library as the main repository for all your Photo Stream photos. You can also choose which photos you want to download from Photo Stream into Aperture, as well as the specific photos in your Aperture library that you want to upload to Photo Stream.

Setting Up Your iCloud Account

You can move your existing MobileMe account to iCloud or create a new iCloud account.

Note: You must have an Internet connection to set up an iCloud account.

To set up an iCloud account
  1. In the Library inspector in Aperture, select Photo Stream.

  2. Click the Turn On Photo Stream button, then click Continue in the dialog that appears.

      Note: For more instructions on setting up an iCloud account, see Mac Help.

You can now return to Aperture to begin working with Photo Stream.

Turning On Photo Stream for an Aperture Library

Photo Stream is designed to work with one Aperture or iPhoto library at a time. However, it’s easy to switch the library Photo Stream uses to upload and download photos.

Important: If you have Photo Stream turned on in iPhoto, turning on Photo Stream in Aperture turns off Photo Stream for your iPhoto library. Photos from Photo Stream are no longer pushed to your iPhoto library.

To turn Photo Stream on or off
  1. Choose Aperture > Preferences, then click Photo Stream.

  2. Do one of the following:

    • To turn on Photo Stream: Select the Enable Photo Stream checkbox.
    • To turn off Photo Stream: Deselect the Enable Photo Stream checkbox, then click Turn Off in the dialog that appears.

To switch Photo Stream to another Aperture library
  1. Open the Aperture library you want to use with Photo Stream.

    Note: For instructions for switching Aperture libraries, see Viewing Other Libraries.

  2. In the Library inspector, select Photo Stream.

  3. Click the Turn On Photo Stream button, then click Switch in the dialog that appears.

Photo Stream is turned on for the Aperture library you switched to and is turned off for the library you switched from. New photos downloaded from Photo Stream appear in the library with Photo Stream turned on, and only photos from that library are automatically uploaded to Photo Stream.

For more information about setting a library to automatically upload photos to Photo Stream, see Automatically Transferring Photos Between Aperture and Photo Stream.

Automatically Transferring Photos Between Aperture and Photo Stream

When you turn on Photo Stream for an Aperture library, Aperture is set to automatically upload photos to and download photos from Photo Stream. However, you can turn these settings on and off. When Aperture is set to automatically download photos from Photo Stream, new photos are imported into a project named “[Month] [Year] Photo Stream.” When Aperture is set to automatically upload photos to Photo Stream, photos are uploaded to Photo Stream as they are imported into Aperture.

Note: To transfer photos between Aperture and Photo Stream, you must have an Internet connection.

To set Aperture to automatically upload photos to and download photos from Photo Stream
  1. Choose Aperture > Preferences, then click the Photo Stream button.

  2. Select the Enable Photo Stream checkbox.

  3. Do either or both of the following:

    • To set Aperture to automatically download photos from Photo Stream: Select the Automatic Import checkbox.

      Note: If you recently switched libraries or have had the Automatic Import feature turned off, only new photos added to Photo Stream are automatically downloaded to your Aperture library. If you want to import the existing photos in Photo Stream, you must manually download them. For more information, see Manually Transferring Photos Between Aperture and Photo Stream.

    • To set Aperture to automatically upload photos to Photo Stream as they are imported into your Aperture library: Select the Automatic Upload checkbox.

Photos remain in your Photo Stream for 30 days and are then removed automatically. You can delete individual photos from your Photo Stream just as you can delete any other Aperture photos, or you can reset your entire Photo Stream—permanently removing all photos—and start over. To reset Photo Stream, sign in to your iCloud account. For more information, see iCloud Support.

Warning: Resetting Photo Stream permanently removes all your photos from iCloud. To avoid losing any photos, make sure you have imported them into your Aperture library or saved them to an iOS device before resetting Photo Stream.

About Enabling Photo Stream on More Than One Mac

You can enable Photo Stream for the same iCloud account on more than one Mac. When you have Photo Stream enabled on more than one Mac and you upload a photo to Photo Stream, Photo Stream includes the Event information from iPhoto or the project information and hierarchy from Aperture. If the receiving application has Automatic Import turned on in Photo Stream preferences, the Event or project information is passed along in one of the following ways:

  • Photo uploaded from iPhoto on one Mac and pushed to iPhoto on another Mac: If the iPhoto library the photo is pushed to contains a duplicate of the Event in which the photo originated, the photo is placed in that Event—even if the Event has been renamed. If the same Event does not appear in the iPhoto library the photo is pushed to, a new Event is created and named after the photo’s original Event.
  • Photo uploaded from iPhoto on one Mac and pushed to Aperture on another Mac: A new project is created in the Aperture library and named after the iPhoto Event in which the photo originated.
  • Photo uploaded from Aperture on one Mac and pushed to iPhoto on another Mac: A new Event is created in the iPhoto library and named after the photo’s immediate parent item in the Aperture library. For example, if the photo originated at the top level of a project named “Travel,” a new Travel Event is created in iPhoto. If the photo originated in an album named “Christmas 2011” that is inside another album or a project, the new iPhoto Event is named after the Christmas 2011 album.
  • Photo uploaded from Aperture on one Mac and pushed to Aperture on another Mac: If the Aperture library the photo is pushed to contains a duplicate of the project or album in which the photo originated, the photo is placed in that project or album—even if the project and any subordinate folders and albums have been renamed or restructured. If the project or its albums don’t exist in the Aperture library the photo is pushed to, the project hierarchy is replicated and the photo is placed in its original position.

Note: When pushing photos to iPhoto or Aperture, Photo Stream downloads photos to iPhoto Events and Aperture projects that have universally unique identifiers (UUIDs) matching those of the photos’ original Events or projects. If you manually create iPhoto Events or Aperture projects with the same names as Events or projects in other libraries, Photo Stream does not recognize those Events or projects as matches. To create matching Events or projects, you must copy them from one library and merge them with the other.

Manually Transferring Photos Between Aperture and Photo Stream

You can choose which photos in your Aperture library you want to upload to Photo Stream. You can also manually download from Photo Stream only those photos that you want to store in your Aperture library.

Note: To transfer photos between Aperture and Photo Stream, you must have an Internet connection.

To manually upload photos to Photo Stream
  1. In the Library inspector, select the item containing the photos you want to upload to Photo Stream.

  2. In the Browser, select the photos you want to upload to Photo Stream, then do one of the following:

    • Choose File > Share > Photo Stream.

    • Click the Photo Stream button in the toolbar.

    • Drag the photos to the Photo Stream item in the Library inspector.

The photos are uploaded to Photo Stream and immediately pushed to the iOS devices connected to your iCloud account. Photos remain in your Photo Stream for 30 days and are then removed automatically. You can delete individual photos from your Photo Stream just as you can delete any other Aperture photos, or you can reset your entire Photo Stream—permanently removing all photos—and start over. To reset Photo Stream, sign in to your iCloud account. For more information, see iCloud Support.

Warning: Resetting Photo Stream permanently removes all your photos from iCloud. To avoid losing any photos, make sure you have imported them into your Aperture library or saved them to an iOS device before resetting Photo Stream.
