Ansel. Open-source photo-editing software for digital artists, based on Darktable. 🐧 Love Open Source 🐧 [View all]

Ansel is what Darktable 4.0 could have been if it didn’t die of feature creep .

YMMV, but I invite comparison between Ansel, Darktable and Raw Therapee as free and open source photo editors for RAW images. Downloads for Linux, Mac and Windows, all three.

Naturally, new software requires some learning curve, despite similarities in the user interface.

Warning
Ansel is in alpha version. The GUI is susceptible to change and the application may crash under some circumstances.


Some very serious thought has gone into this software. Here's a long discourse on color controls.
