Lightroom is still the go-to editor for many people who shoot RAW photos. But it comes with an expensive subscription and the desktop version feels increasingly neglected in favor of its cloud-based companion. If you’d rather keep your files on your own computer instead of syncing everything online, darktable is one of the best free alternatives.
The search for a Lightroom alternative
Most fall short in one way or another
Lightroom Classic is still the best RAW editing and management program. But if you don’t want to pay a subscription, and don’t need the cloud features and the lock-in that comes with that, you need to look elsewhere. I gave up on it quite a few years ago, and have been on a constant hunt for an open-source alternative to fully replace it.
The relative newcomer RapidRAW looks extremely promising. It’s a small app with GPU-accelerated processing, and feels fast and responsive. The UI is very much inspired by Lightroom, which makes it highly accessible, especially to anyone who just wants a simple editor. It isn’t ready to go all-in on just yet, not least because it’s in active development and is changing constantly, but it is one to keep an eye on.
Library management is a big part of the Lightroom experience. There are lots of RAW processors, but having a fully integrated system of managing and editing is harder to come by. I also like the free (but not open-source) Affinity for editing, but it has no asset management features so cannot be a complete replacement.
The Lightroom alternative that I’ve opted for is darktable. It’s free and open-source, and is very mature. It’s been around since 2009. Because darktable runs entirely on your own computer, your RAW files and edits stay under your control rather than being tied to a subscription service.
As well as being a powerful RAW editor, it has got the digital asset management features nailed. Although you can’t import a Lightroom catalog specifically, darktable will check for and use XMP sidecar files from Lightroom files. They aren’t fully compatible, but you keep some of your edits along with things like tags and ratings. It makes it a little easier to switch.

Although it comes with a learning curve
If you haven’t used darktable before, there’s something you should know right from the start. It comes with a pretty hefty learning curve. In fact, it isn’t quite as difficult as it looks when you first open it, but your first couple of hours will be pretty tough.
Lightroom guides you through the editing process. It labels its tools clearly and orders them in a way that’s somewhat logical for a basic workflow, starting with the most common edits then leading to the more advanced things. darktable, by comparison, has the classic open-source vibe. It’s packed with tools, they aren’t always obviously named, and some crop up in more than one place.
In some cases, the confusion is simply because the tools have different names. White balance is called color calibration, for instance. In other cases, it’s because darktable approaches editing differently from Lightroom. Instead of hiding advanced features away, it puts a huge amount of control right in front of you from the start.
But as you start to use the app, it becomes less intimidating and more familiar. There’s the Lighttable mode for library management, where you can create collections and tag, filter, and rate your photos. You use Darkroom mode for processing. All the edits are non-destructive, so you can experiment as much as you like, and undo them all if you don’t like them.
Masks are an example of a tool that’s complicated in darktable because they’re so powerful. Instead of the simple adjustment brushes of Lightroom, you can apply a mask to almost any setting in darktable. You can draw the mask, use shapes, or even base it off color or brightness values. This makes selective editing harder to learn, but also more flexible once you get how it works.
There are things that Lightroom doesn’t have. darktable’s modern scene-referred workflow gives it excellent highlight recovery and more natural tonal transitions, especially in high-contrast images. The modular design also means you can use multiple instances of the same tool for more complex processing.
A few simple tweaks make darktable more accessible
You can make it a lot easier to use
darktable looks daunting when you first install it. It becomes better with a little familiarity, but you’ll find yourself discovering new features and new ways to do things for a long time.
To help get started, change the waveform to the histogram in the top right corner. Below that, click the rightmost button on the toolbar and select Workflow:Beginner to see a simplified set of tools to help ease you in.
The first button on the toolbar—the quick access panel—is where you’ll find simplified versions of the most common everyday tools. Click the button on the right edge of each one to see a more powerful version with more options. The second button shows only the modules (the settings) that are currently applied to the image, and then the Base modules, which are the basic tools you need to process any image.
Ease yourself in
The best way to approach darktable is to ease yourself in. Don’t worry about mastering it in one go, and if you’re coming from Lightroom, accept that it does things differently. Instead of trying to find direct equivalents for everything, figure out and embrace how darktable does something, and you’ll soon be on your way to mastering this incredibly powerful free Lightroom replacement.
