An Overview of Exporting Images

Using Aperture, you can export copies of masters, as well as versions that you’ve created. When you export image versions, you can export them in JPEG, TIFF, PNG, and PSD file formats.

At export, you can rename files, resize and adjust images, and include metadata such as EXIF information, IPTC information, and keywords. You can also apply ColorSync profiles and watermarks to the versions you’re exporting. You can export separate lists of metadata for selected images as a file. You can also export masters with IPTC data stored in XMP sidecar files that can be used in other applications, such as Adobe Photoshop.

Before exporting your images to another application, a printing service, a client, or a website, you need to know what file types the recipient can use. You should also check with the recipient about other important information, including file size limitations, required image dimensions, and naming conventions. The key to a successful file transfer is anticipating—and avoiding—anything that can prevent the recipient from opening your files.

Aperture allows you to perform multiple export operations concurrently. However, it’s extremely important that you avoid making changes to the images you are exporting until the operation is complete to prevent unintended behavior.

The easiest way to export images is to use one of the Aperture export presets. Presets, or groups of export settings, allow you to efficiently export your images. If the presets included with Aperture don’t meet your needs, you can create your own. For example, if you regularly send groups of photos to a stock photography house and a printer, you can create an export preset for each destination. Give the presets a name you’ll remember, and the next time you need to send images to either destination, simply select the correct export preset.

You can also modify existing export presets and delete export presets you no longer use.

Exporting Images to an External Editor

Aperture provides an easy way to transfer images to another application for changes and then bring the revised images back into Aperture. You can specify an application as an external editor in the Export pane of the Preferences window. For example, if your image editing sometimes requires one or more of the specialized tools available in Adobe Photoshop, you can select Photoshop as your external editor. You can then select an image and choose Photos > Edit With > [application name]. Aperture makes a new master and version of your image and opens it in Adobe Photoshop. After you make your changes and save the image, the revised version automatically reappears in Aperture. The external editor doesn’t change the original master.
