Installation Methods

There are several ways to install RawTherapee on Fedora 41. We’ll cover three primary methods: using the DNF package manager, Snap, and AppImage.

Method 1: DNF Package Manager Installation

The DNF package manager is the preferred method for installing software on Fedora. It’s straightforward and ensures you get the version compatible with your system.

1. Open your terminal.
2. Run the following command to install RawTherapee:

sudo dnf install rawtherapee

This command will automatically download and install RawTherapee along with its dependencies. As of Fedora 41, you’ll get RawTherapee version 5.11.

To verify the installation, you can run:

rawtherapee --version

Method 2: Snap Installation

Snap packages offer the advantage of easy updates and containment. To install RawTherapee using Snap:

1. First, ensure Snap support is enabled on your Fedora 41 system:

sudo dnf install snapd
sudo systemctl enable --now snapd.socket
sudo ln -s /var/lib/snapd/snap /snap

2. Once Snap is set up, install RawTherapee with:

sudo snap install rawtherapee

Note that you may need to log out and back in for the Snap paths to update correctly.

Method 3: AppImage Installation

AppImage provides a portable version of RawTherapee that doesn’t require installation. Here’s how to use it:

1. Download the latest RawTherapee AppImage from the official website.
2. Make the AppImage executable:

chmod +x RawTherapee_5.11.AppImage

3. Run RawTherapee:

./RawTherapee_5.11.AppImage

For convenience, you can create a desktop shortcut or move the AppImage to a directory in your PATH.

Post-Installation Setup

After installing RawTherapee, it’s crucial to configure it for optimal performance:

Color Management Setup

1. Open RawTherapee and navigate to Preferences > Color Management.
2. Enable “Use operating system’s main monitor color profile” for accurate color representation.
3. If you have a calibrated monitor, specify your custom ICC profile here.

Interface Customization

1. Go to Preferences > General.
2. Under “Appearance,” choose a theme that suits your workflow. The “TooWaGrey – Average Surround” theme is recommended for its neutral gray background, ideal for color-critical work.
3. If using a high-DPI display, enable “Pseudo-HiDPI mode” for better UI scaling.

Performance Optimization

1. In Preferences > Performance, adjust the “Processing threads count” based on your CPU’s capabilities.
2. Set an appropriate “RAM cache size” to balance performance and memory usage.

Essential Configuration for Fedora 41 Users

To get the most out of RawTherapee on Fedora 41, consider these additional configurations:

Setting Up Color Profiles

Fedora 41 comes with a set of color profiles, but you might want to install additional ones:
