Aperture Exporter
There are plenty of guides on the internet detailing how to get your images out of Aperture and into another photo manager such as Adobe Lightroom. It’s a multistep and complicated process that is easy to get wrong. Aperture Exporter consolidates the process into just a few clicks and provides features not possible with any manual process.
Aperture Exporter is also a great way to back up your Aperture Libraries in a format that is not reliant on the future use of Aperture.
Exporting will always generate files for your originals without adjustments. Versions with Aperture adjustments baked-in can be generated optionally.
