Export by dragging
You can export photo, audio, and video versions by dragging them from the Browser to the desktop or any location in the Finder. You can do the same with projects, albums, and folders in the Library inspector. (Flickr and Facebook albums cannot be exported by dragging.)
When you export a photo by dragging, you’re exporting its optimized JPEG preview image (at the quality and size specified by the Previews settings in Aperture preferences). If you want to export in any other format or quality, you must use the Export command described in Export using the Export command. For more information about JPEG previews, see Preview images overview.
Note: A photo version without a JPEG preview cannot be exported by dragging. If the version doesn’t have a preview, dragging is disabled for that version (except within Aperture). If you are dragging multiple photos, but only some of them have previews, only the versions with previews are dragged out.
Export versions from the Browser by dragging
In the Browser, select the photo, audio, and video versions you want to export.
Drag the versions to the desktop or any location in the Finder.
Export items from the Library inspector by dragging
In the Library inspector, select the items you want to export by Shift-clicking adjacent items and Command-clicking nonadjacent items.
Drag the items to the desktop or any location in the Finder.
The exported items are consolidated into a single Aperture library. The library is named after the item that appears at the highest point (from top to bottom) in the Library inspector. If an album is selected for export, the album and the project to which it is subordinate are exported, but only the versions within the album are exported. Any other photos in the project are left out of the export.
If you want to rename the exported library, click the file, then click its name and enter a new name.
WARNING: In rare instances, color shifts between exported photos may occur when the Camera Previews option is selected in the Import pane of the Aperture Preferences window. This color shift happens because some RAW photos have fully rendered previews, and others still use the camera’s RAW thumbnail. To prevent this from happening, view all photos you want to export in the Viewer, and Aperture generates a fully rendered preview for each photo. For more information, see Preview images overview and Import preferences.
