If you want to import raw files into Aperture that you have already edited with Photoshop Camera Raw, (or perform some other action on those files using Automator – such as zipping or uploading) then the Pass Only Raws Automator Action might ease your migration.
If you’ve got a lot of raw files, it can be time consuming to sort through which ones you have already selected and deemed worthy of further editing.
But, if you’ve already sorted through those files and processed them in Photoshop Camera raw, and if you’ve got your Camera Raw preferences set to create sidecar XMP files, then this action will greatly speed your importing.
To use the action, (available below for free download) use a Get Specified Finder Items action to select a batch of files (of course, if you’re making this action part of a larger workflow, then you might be passing files from a different action).
Next, add the Pass Only Raws with XMPs action. You’ll find it listed in the Finder action library. Configure the Pass Files of Type pop-up menu to the extension that your raw files use.
The Pass Only Raws action will produce a list of new files that you can pass on to the rest of your workflow.
