Wrapping Up

With Aperture's round-trip capability, you can look at your other image editor as a very capable plug-in to Aperture. If there's an edit you need to make using a tool in your external editor, just select the image you want to edit, press Command-Shift-O, make your edit, and save, and in no time you're back in Aperture with your edited image. As you work with the Aperture round-trip feature, you'll soon be able to plan which edits to make in Aperture and which to make externally.
