There are plenty of excellent free photo editing programs available, such as RawTherapee, Darktable, and DigiKam, to name a few. But whether they suit your needs is something only you can determine. Even if a program is widely praised or deemed “the best,” it’s the subtle differences between them that ultimately matter—and those differences can be significant.
In a previous article, I wrote about RawTherapee but didn’t mention another fantastic free program: GIMP. Often hailed as the best free alternative to Photoshop, GIMP lives up to this reputation—confirmed even by publications like Amateur Photographer.
So why didn’t I bring it up earlier? One reason is that Darktable deserves mention too. Darktable has a dedicated following, and for good reason: it takes things further where RawTherapee stops. That said, RawTherapee has a hidden strength: its ability to export files directly to external programs like GIMP. While earlier versions had a dedicated GIMP link, you can now configure it yourself—and even link it to multiple programs!
This makes RawTherapee incredibly versatile. Its strengths extend beyond its built-in features because you don’t always need advanced tools like GIMP or Photoshop, but they’re just a click away when you do. For example, with one click, RawTherapee can send a TIFF file to GIMP for further editing.
As for GIMP itself, it’s a powerhouse of possibilities. You can expand its functionality with plugins, such as the comprehensive G’MIC-Qt suite, adding even more tools to your arsenal. Everything you can do in Photoshop is also possible in GIMP—though the methods may differ. However, both programs share a steep learning curve. Mastering either requires time and dedication. Personally, I turn to GIMP for specific tasks where it truly shines. For instance, I use it to remove unwanted elements from photos, work with layers to simulate color effects or filters, enhance HDR images by blending multiple layers, and even perform focus stacking. Its versatility makes it a fantastic tool for these specialized techniques! When I want to try something new, I experiment first; if that doesn’t work, I rely on one of the hundreds (if not thousands) of instructional videos available on YouTube.
A note of encouragement: Don’t be intimidated by the complexity of these programs. Don’t let differences from what you’re used to hold you back, either. Every program comes with a learning curve, and the same was true for the software you’re currently using. With time and patience, you can master any tool—and these free options are worth the effort.

90% of my RAW Editing is done in RawTherapee – the rest in Gimp
Most of my RAW photo editing happens entirely in RawTherapee, with only a small percentage requiring extra adjustments. These usually involve removing distracting elements or making creative tweaks—like repositioning the black swan in this particular example.
I also enjoy experimenting with layers. For instance, one of the photos in my gallery features a mystical monk appearing in a large round chapel window. Another creative project took place after visiting the site of a former castle, now reduced to just its foundations. Using an old photograph, I tried to “rebuild” the castle digitally, placing it back in its original environment.
It’s the kind of Photoshop wizardry people love, but why spend money on Photoshop when GIMP is free and just as capable? I think it’s absolutely worth giving a try!

I’m really looking forward to Gimp 3, even though I use Photoshop now, I do like Gimp, and with it’s new features that will be fully realised in Gimp 3, I think it’s going to be amazing.
