There has been a major update of RapidRAW, and we are now on RapidRAW version 1.6.7. This update concentrates on improving RapidRaw’s core performance in colour management and various AI tools. It is a welcome upgrade to the software.
What Is RapidRAW 1.6.7?
RapidRAW 1.6.7 is a major release of the open-source, lightweight, GPU-accelerated non-destructive RAW photo editor. Available for Windows, macOS, Linux, and Android under the GPL license, this update moves RapidRAW further from a quick viewer into a fully featured Lightroom alternative.
1. Deep Immich Integration
RapidRAW 1.6.7 brings native integration for self-hosted Immich photo libraries:
- Direct Library Browsing: Navigate Immich albums, timelines, and RAW stacks directly inside the RapidRAW interface without pre-downloading catalog files.
- Two-Way Background Sync: Metadata, star ratings, and adjustments automatically sync to the Immich server in the background every few seconds. If offline, edits queue locally and push when connectivity is restored.
- Direct Export to Immich: Export edited photos straight to an Immich album, where they are automatically stacked alongside the original file.
- Secure Token Storage: API keys are stored securely using platform native keychains (Windows Credential Manager, macOS Keychain, Secret Service, or Android Keystore).
2. Overhauled AI Denoise & Background Job Queue
- Non-Destructive GPU AI Denoise: The legacy modal interface that exported intermediate TIFF files has been completely removed. AI Denoise now processes GPU-accelerated adjustments directly within the editing pipeline.
- Batch Copy & Paste: Denoise settings can now be copied and pasted across multiple photos.
- Global Background Job Queue: Heavy background processes (AI Denoise, export, thumbnail generation) are consolidated into a centralized UI Job Queue.
- Classic Denoise (AI-Free Mode): For users running without AI acceleration, the Details panel features a fast, non-destructive BM3D-based Classic Denoise algorithm.
3. Color Accuracy & Engine Improvements
- Dual-Illuminant Color Profiles: RapidRAW 1.6.7 supports dual-illuminant camera color calibration matching the DNG standard. White balance automatically interpolates between daylight and tungsten profiles to eliminate magenta/purple color casts in artificial lighting.
- Gamut Compression: Highly saturated colors that exceed sRGB or target color space bounds are compressed smoothly rather than hard-clipped, preventing color banding and artifacting in neon signs or stage lighting.
- On-Demand AI Models: AI model downloads (for sky/subject masks and denoise) now download dynamically upon first use rather than requiring large upfront bundle downloads.
4. Enhanced Editing Tools & Workflow
- Flexible Compare Modes: Toggle side-by-side, split left/right, and split top/bottom before/after views by right-clicking the compare icon or pressing
B. - Non-Destructive Film Negative Conversion: The film negative tool is integrated directly into the Details panel. Non-destructively tweak RGB channel balance, print exposure, and print grade, or convert film negatives in batches via the context menu.
- Expanded Batch Adjustments: Lens Blur, Atmospheric Fog, 3D Relight, and AI Denoise are integrated into the global Copy/Paste dialog.
- Improved AI Sky & Foreground Segmentation: Fine structures such as hair, power lines, and tree foliage are separated with higher edge fidelity.
5. Performance & Memory Optimizations
- Lower Memory Footprint: Reduced RAM consumption across the preview pipeline, adjustment layers, AI masks, and the main user interface.
- Decoded Image Reuse: Decoding cached image buffers prevents duplicate decoding steps when using the Culling View, Collage Tool, and Tethering modes.
