Lumen: an offline culling bench for Sony RAW
A free, open-source app for grouping, reviewing, tagging, and exporting Sony RAW photos on Apple Silicon Macs, with processing kept local.
- For
- Wildlife photographers using Sony cameras on Apple Silicon Macs
- Worth noticing
- Amber marks the photographer’s decision; cyan marks local-model advice, and the model never makes the final keep-or-reject choice.
Field notes
The walkthrough frames each burst as a row: amber marks the photographer’s choice, while cyan marks a local model’s suggestion. The page describes sharpness scoring, burst grouping, mapping, tagging, and export as on-device operations, with originals left untouched and generated material kept in a separate discardable library. Its examples include 692 frames from one cheetah morning and 482 across two days at South Georgia; the site says support for Canon, Nikon, and Leica RAW files is still forthcoming.
