Reprocessing Images from Previous Versions of Aperture

Aperture provides image processing algorithms that deliver improved image quality. With improved default rendering of RAW images from supported cameras, Aperture 3 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 allows you to retain the original processing of your images from previous versions, selectively process images using the new Aperture image processing, or create duplicate versions of each original image file with Aperture image processing applied. However, some adjustments and brushed adjustments are not available unless the selected image uses Aperture 3 image processing.

Strategies for Reprocessing Images

When you start using Aperture, all of your existing images continue to use the previous version’s image processing, in order to preserve their appearance. Any of these images can be individually reprocessed to use the Aperture 3 image processing. You can also use the Reprocess Masters command in the Photos menu to reprocess selected images, projects, books, slideshows, webpages and web journals, Light Table albums, albums, and Smart Albums.

Reprocessing a large number of images can be a time-consuming process. Therefore, you may find it easier to reprocess images on an as-needed basis. For example, if you have five-star selects, you may decide to initially reprocess only those images. Images are not affected by being reprocessed more than once; if an image already uses Aperture 3 image processing, reprocessing it again has no effect.

Reprocessing an Image Selection

You can reprocess all images, reprocess only images with adjustments, or reprocess only images without adjustments. You can also reprocess images one at a time using the RAW Fine Tuning controls in the Adjustments inspector or the Adjustments pane of the Inspector HUD. For more information about reprocessing individual images, see Reprocessing Images Individually.

To reprocess a selection of images
  1. Select an image or a group of images.

  2. Choose Photos > Reprocess Masters.

  3. In the dialog that appears, select the appropriate reprocessing criteria, then click the Reprocess Photos button.

The image files are reprocessed from the earlier image process to Aperture 3 image processing, according to the criteria you specified.

You can also reprocess all the images in a selected project, book, slideshow, webpage, web journal, Light Table album, album, or Smart Album.

To reprocess a project or album
  1. In the Library inspector, select a project or album.

  2. Choose Photos > Reprocess Masters.

  3. In the dialog that appears, select the appropriate reprocessing criteria, then click the Reprocess Photos button.

    Figure. Reprocess Photos dialog.

All images in the selected project or album are reprocessed using Aperture 3 image processing.

If you like, you can reprocess all the images in the library at once. However, this process may take a long time for large libraries.

To reprocess every image in the library
  1. In the Library inspector, select the Photos item.

  2. Choose Photos > Reprocess Masters.

  3. In the dialog that appears, select the appropriate reprocessing criteria, then click the Reprocess Photos button.

Every image in the library is reprocessed using Aperture 3 image processing.

Important: Reprocessing thousands of image files to Aperture 3 can be a lengthy operation. Make sure to set aside a significant amount of time for Aperture to process the image files—preferably when you don’t require the use of your Aperture system.

Reprocessing Images Individually

You can reprocess images one at a time using the Adjustments inspector or the Adjustments pane of the Inspector HUD.

To reprocess an individual image
  1. Select an image.

  2. In the Adjustments inspector or the Adjustments pane of the Inspector HUD, click the Reprocess button.

    Note: If the Reprocess button does not appear in the Adjustments inspector or the Adjustments pane of the Inspector HUD, the image has already been reprocessed using Aperture 3 image processing.
