RawTherapee is a powerful, open-source photo editing software known for its advanced features and high-quality output.

Understanding Chrome OS

Before diving into the installation process, it’s beneficial to understand Chrome OS and its unique environment.

However, the limitations of the operating system often mean some native applications don’t function as they would on traditional operating systems.

Linux Apps on Chromebook

One of the standout features of modern Chromebooks is their support for Linux applications. This is particularly advantageous for users who want to leverage the versatility of Linux-based software, like RawTherapee. To install and run these applications, you’ll need to enable the Linux (Beta) feature on your Chromebook.
