External Editors For Photos (EEFP) adds an extension to the OS X Photos application that allows you to edit your photos with any image editor on your Mac. To see how it works watch the screencast.

How it works:

  • EEFP tries to find every app that can handle the current image, but lets you also have a list of your favorite editors that you can manage yourself.
  • If you have a workflow that starts with a folder you can copy images from the extension into any folder you like.
  • Edited images are saved back to Photos immediately and your original photos are updated in place.
  • All metadata will be preserved.
  • Open your imported RAW files with your favorite RAW-Converter and replace it with an exported JPEG by clicking Replace With Image From Disk.
  • No data lost: You can always revert back to your original files.
  • Works even in your book-projects.
  • Edited Photos will sync across all your devices.

Usage:

  • To use the extension find a picture in Photos and double-click
  • Click the Edit button in the upper right window corner
  • Select Extensions from the icon bar on the right.

Tipps:

  • Pressing Enter in the photo overview is a shortcut to switch directly into Photos Edit Mode.
  • Also, you can paste or drag any image into the picture frame within the extension.
