Approximately a month after Apple announced it is discontinuing Aperture and iPhoto in favor of the new Photos app on OS X Yosemite and iOS 8, Adobe is today taking advantage of the Apple shift with a couple of key announcements. First, Adobe has published a new website detailing the advantages of Lightroom over Aperture. More importantly, Adobe has released a comprehensive, step-by-step transition guide for moving from Aperture to Lightroom. The guide also includes some answers to frequently asked questions.

At Adobe, we’re working on a migration tool to help you bring your photos into Adobe® Photoshop® Lightroom® from Aperture, but if you’re eager to switch before the tool is ready, this guide can help ease your transition. We recognize that this migration may be a challenging process and offer the following resources and methodology to help get you up to speed with Lightroom and provide a road map for successfully migrating your photos.

The first challenge is that the terminology, layout, and controls of the two applications are different. It’s a good idea to start processing photos in Lightroom and become familiar with it before you migrate your photos from Aperture. You can do so by taking some new photos, importing them into Lightroom, and then using Lightroom.

The new Photos app for OS X launches in early 2015, but despite Apple’s claims of significant functionality, a look at what Apple has shown about the app reveals that the functionality mostly mirrors what iOS 8 will gain in September. Adobe has also previously detailed some future Lightroom plans in order to appease professional photo editors.
