RapidRAW is een modern, krachtig opensource alternatief voor Adobe Lightroom. Het levert een eenvoudige en mooie bewerkingservaring in een lichtgewicht pakket van ongeveer 20MB voor Windows, macOS en Linux. Het wordt ontwikkeld door een 18-jarige Zwitser, die hier juli 2025 mee is begonnen als een persoonlijke uitdaging met als doel om een krachtige programma te creëren voor zijn eigen fotografieworkflow. RapidRaw is gebouwd met een Rust-backend en een React/TypeScript-frontend, verpakt met Tauri om hem licht te houden. De meest recente uitgave is versie 1.4.4 en hier zijn de volgende verbeteringen in aangebracht:
AgX Color ManagementLike in Blender and darktable, RapidRAW now supports the advanced tone mapper AgX. A thank you to darktable, Blender, and other open-source projects for providing reference implementation details and inspiring this integration.
Reworked Exposure ControlsAlongside the new tone mapper selector, the exposure controls have been significantly improved. The previous single slider has been split into two more powerful and intuitive controls:
Copy & Paste Settings
- Exposure: This slider now acts as a true exposure compensation, shifting the entire histogram. Use it to set the correct technical exposure for your scene.
- Brightness: This slider, which functions like the old exposure control, primarily adjusts the mid-tones. Use it to fine-tune the perceived light in the image after setting the base exposure.
You can now selectively copy and paste adjustments between images. This new setting gives you much better control when applying adjustments from one image to another, ensuring you only transfer the exact changes you want. Key features include:
Processing Engine Settings
- Selective Adjustments: Instead of an all or nothing paste, you can now individually select which adjustments to apply.
- Powerful Paste Modes: Choose how your selected settings are applied:
- Merge: Adds your copied changes on top of the destination image's existing edits, leaving other settings untouched.
- Replace: Applies the selected adjustments and resets any unselected adjustments on the destination image to their default values. This is perfect for creating a consistent look from a clean slate.
A new Processing Engine Settings section is now available, giving you direct control over core processing options. You can now manually select the processing backend for performance tuning or troubleshooting. Additionally, a Linux GPU Compatibility Mode has been included to resolve stability issues and artifacts reported by some Linux users (as detailed in issue #306).
Core ImprovementsHighlight Recovery Value Comparison
- Moved more core parts from 8-bit (u8) to 32-bit float (f32) for increased precision.
- Improved accuracy of the Color Mixer, which may cause some HSL-related edits to appear slightly different.
- Faster image loading times.
- RAW highlight recovery is now adjustable via the processing engine settings.
High highlight recovery values can cause purple artifacts on some cameras, while lowering the value reduces artifacts but may also remove some highlight detail.
