In this guide, we will show you how to install RawTherapee on Ubuntu Systems.

RawTherapee is application software for processing photographs in raw image formats, as created by many digital cameras. It comprises a subset of image editing operations specifically aimed at non-destructive post-production of raw photos and is primarily focused on improving a photographer’s workflow by facilitating the handling of large numbers of images. Also, it is notable for the advanced control it gives the user over the demosaicing and developing process. It is cross-platform, with versions for Microsoft Windows, macOS and Linux.

So, RawTherapee was originally written by Gábor Horváth of Budapest, Hungary, and was re-licensed as free and open-source software under the GNU General Public License Version 3 in January 2010. It is written in C++, using a GTK+ front-end and a patched version of dcraw for reading raw files. The name “Therapee” was originally an acronym derived from “The Experimental Raw Photo Editor”.
