External Editors For Photos 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 on my website. Features: - 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 your edited version. - 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 the Extensions from the icon bar on the right. Tipp: - 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. Have Fun!
