Lumen

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

  • Rust
  • CLI
  • EXIF

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.
