RW2 (camera RAW)
What is an RW2 (camera RAW) file?
The RW2 file extension is the successor to the RAW format, used exclusively for raw images produced by Panasonic Lumix digital cameras. It stores unprocessed data from the image sensor along with a unique header containing metadata such as lens information, shutter speed, ISO settings, and color profile tags. The format allows for non-destructive editing by saving parameter adjustments as sidecar files or database entries rather than altering the original pixel data. It typically employs a proprietary lossless compression algorithm.
How to open an RW2 (camera RAW) file
RW2 files are supported by professional post-production software including Adobe Photoshop (Camera Raw plugin), Adobe Lightroom, and DxO PhotoLab. Panasonic bundles the SILKYPIX Developer Studio software with their cameras for native decoding. Windows 10 and 11 users can view these files in the Photos app after installing the Raw Image Extension. macOS users can preview and edit RW2 files natively through the Preview app and Photos app, leveraging Apple's system-level raw engine.
