How to Install RawTherapee 5.3 on Ubuntu 16.04, 17.04, 17.10

    RawTherapee is a powerful, cross-platform raw photo processing program, released under the GNU General Public License Version 3 and written in C++ using a GTK+ front-end. It uses a patched version of dcraw for reading raw files, with an in-house solution which adds the highest quality support for certain camera models unsupported by dcraw and enhances the accuracy of certain raw files already supported by dcraw. It is notable for the advanced control it gives the user over the demosaicing and development process.
