Margins are minimized to optimize the use of smaller displays.
Sliders and Controls
The sliders have been reworked for better readability. There is more space between the label and the baseline, and the cursor is larger and better separated from the background. For gradient sliders, the cursor is hollow to show the color through. The fill-in bar starts from the “0” value, which is more natural for balance sliders, and the neutral position is emphasized with a dot.
Theme Customization
Darktable is now fully themeable, with all styling rules moved to GTK’s CSS stylesheet. Users can select themes from the preferences, and a grey theme is also available. This customization ensures that the interface adapts well to different user preferences and display settings.
User Experience
Despite its advanced features, Darktable is relatively easy to use once you get familiar with its architecture. It is heavily customizable, but most users can manage with a small collection of modules that cover their primary needs. The software leaves all editing choices up to the user, which can initially make raw files appear dark and flat, but this is part of its philosophy to give users full control over their edits.
Recent Improvements
In the latest version, Darktable 5.0, several UI and UX enhancements have been introduced. These include new camera-specific styles for over 500 camera models, improved UI during bulk imaging operations, a new high contrast theme, and drag-and-drop improvements. Additionally, there are more hints for new users and significant performance optimizations, such as faster loading of PFM files and improved bulk image operations.
Keyboard Shortcuts and Customization
Darktable supports extensive keyboard shortcuts, which can be customized to fit individual workflows. The software also allows for adding custom UI elements through Lua scripts, enabling users to personalize the interface further.
Conclusion
Overall, Darktable’s user interface is designed to be clean, efficient, and highly customizable, making it a versatile tool for photographers who value control and flexibility in their editing workflow.
