Pixelmator Pro Brings Powerful Editing Tools to Apple’s Photos App

You have long been able to use external photo editors with Apple Photos, but the release yesterday of Pixelmator Pro has made Apple Photos a much more powerful photo editing tool. When you open a photo in other external photo editors via Photos, make changes to the photo, then the finished photo is saved back to your Photos library. If you want to go back and tweak your changes – say you want to adjust your exposure a bit more, or change the saturation – you either work on the edited photo or you start over from your original.


With the new Pixelmator Pro, your edit history is saved, and when you re-open a photo you edited with it as an external editor, you can go back and tweak any of the adjustments you have made. This is a game-changer for Apple Photos, and it now provides the best of both worlds: simple photo library management, including in the cloud, and powerful editing capabilities. (To access a photo editing extension, select a photo and press Return to open it in Edit mode, then click the little circle with ellipsis icon and choose Pixelmator Pro.)


Pixelmator Pro’s ML Enhance (ML for machine learning) is an interesting tool that can automatically optimize your photos. Similar to clicking the magic wand in Apple Photos, or other automatic adjustments in various photo editing apps, I find that it is sometimes a bit heavy handed, but for many people, this is an excellent way to enhance photos. I found it especially good at correcting the white balance and skin tone in this photo, which I shot with my iPhone the other day.


However, I wish Pixelmator Pro had automatic adjustment options for individual adjustments. For example, in Apple Photos, I can click Auto buttons for Light, Color, Black & White, White Balance, and more. Each group of tools has an Auto button. With Pixelmator Pro, there are “ML” buttons for some tools – the ones that display by default – but not all. For example, I recently learned how the Curves tool in Apple Photos can help improve the contrast and dynamic range in my photos; I now often use the Auto button to see how this looks. In Pixelmator Pro, there is no such option for Curves, Levels, or even Black & White.

While Pixelmator Pro’s auto-adjustments are useful, the real power comes in the wide range of editing tools available. You need to take some time to explore the interface.

By default, only a few adjustments are displayed, but if you click Add at the top right, you discover a menu with more than 15 tools. And when in the Add Effects tool, clicking Add displays ten menus with dozens of options (including vignette, which is one I use often, though subtly).

If, like me, you appreciate Apple Photos as a way of managing your photo library, and making it available across devices, but still want more powerful photo editing, then Pixelmator Pro used as an extension is a great addition to this app. The ability to return to your photos and adjust your edits is powerful, and I would expect other photo editing tools to try to emulate this as well.

For more on photo editing apps for Mac – Pixelmator Pro, Luminar, Affinity Photo, RAW Power, Capture One, and others, check out this episode of the PhotoActive podcast, where my co-host Jeff Carlson and I discuss the many options available. I wish this version of Pixelmator Pro had been available when we recorded the episode; our discussion would have been quite different.
