Lumen
A tiny CLI for batch-renaming and tagging RAW photo files by EXIF data.

This is sample content. Replace it with your own write-up, or delete the file.
Why
Camera filenames like DSC_0412.NEF tell you nothing. Lumen renames them by capture
time, camera body, and lens, and writes sidecar tags so your editor can filter by them.
lumen rename --pattern "{date}-{camera}-{seq}" ./import
Notes
Describe the architecture, the interesting problems, and the result.
