Apple released the OS X Yosemite 10.10.3 update today, which includes the new Photos app, which will replace my beloved iPhoto as well as Aperture, for photo management on the Mac. There’s a lot of coverage on the new app, so I’m not going to do a full review- just the conclusion. I’ve been using the developer preview (on a secondary machine) for a while, and I think it’s a good app and a suitable replacement for photo management on the Mac.
Except for one inexplicable, deal-killing omission. There is no longer an easy way to edit photos in an external editor.
In iPhoto, it was so, so simple to open photos in an external editor- in my case, the wonderful Pixelmator– edit them, and immediately save them back to iPhoto. Just a few keyboard clicks, and the edited photo was back in its proper place in your iPhoto album.
The process for doing this in the new Photos app, well, doesn’t exist. You have to manually export the photo, open it in the external editor, edit it, save it and re-import it into the Photos app. This is simply unworkable.
In prior instances, Apple has added missing features to new or redesigned apps via updates. They will need to add back the ability to easily edit in an external editor before the Photos app will be a candidate to manage my photo workflow.

Yep, Apple sucks these days. I have been an Apple user since 1983 and a huge evangelist. But the last 8 years I have grown to really detest Apple. They do not give a crap about professionals or enthusiasts anymore. Apple is the new Microsoft.
