DNG Conversion

There is currently no way to import the data in XMP sidecar files into Aperture. There is a work-around that will enable you to import the files into Aperture complete with IPTC metadata and keywords intact, though not ratings. This involves converting your camera Raw files to Adobe DNG format.

DNG is Adobe's Digital Negative format, an open and published alternative to proprietary camera Raw formats. For more detailed information about the DNG format see Chapter 1. To convert your camera Raw files to DNG you'll need Adobe's DNG Converter application which you can download free from the Adobe

Fig. 7.10 This is what you'll find if you open an XMP file in a text editor. This section of the file contains the Exif information, further down is the IPTC metadata and the list of adjustments made in ACR.

containing the images to be converted. Make sure the .xmp files are in the same folder as the Raw files. Check the box to include images contained within sub-folders. In panel 2, select Save in New location from the pop-up menu and choose a folder in which to save the converted images. Check the Preserve sub-folders box. In panel 3 leave everything as it is, so that your files keep their name but are appended with the .dng file extension.

When you click the Convert button, DNG converter will begin the conversion process. You can convert your entire image Library to DNG this way, but it may take a while. Before you embark on a large scale conversion you may want to try a test with a single folder of images. As long as you have a safe backup of the original Raw files and you save the converted files to a new location with a .dng suffix, you've got nothing to lose and can always revert to your camera Raw files if you decide against using DNG in future.

When the conversion process is complete, you'll have a duplicate of your image Library with the same file and folder structure containing .dng rather than camera Raw and .xmp sidecar files.

Fig. 7.13 When you click the Convert button, DNG converter will begin the conversion process. For a large Library this could take some time. Do a test run on a small folder of images to ensure everything works as expected.

DNG converter automatically embeds the metadata that was in the sidecar file into the .dng file (Figs 7.12-7.14).

Now you're ready to import the .dng files into Aperture. Select File > Import > Folders Into a Projectand navigate to one of the converted folders. Aperture imports all of the images into a single Project and creates Albums for sub-folders, so you might first want to decide how you want your Projects organized in the Projects Inspector and set up a suitable folder structure.

When Aperture imports the .dng files it also imports the IPTC metadata and keywords. It's not possible to import image adjustments made to Raw files in ACR, even DNGs into Aperture. Although ACR saves the adjustments to the XMP sidecar file or, if possible, the file itself, and they are imported into Aperture, they

are immediately overwritten by the Aperture Raw decoder and default adjustment settings.
