Who it is forA Lightroom Classic user who wants to leave the subscription but keep years of edits, keywords and presets.

The problemRe-doing edits, keywords and collections by hand across a large catalog takes days.

The outcomeYour Lightroom Classic catalog's edits, keywords, labels, virtual copies and collections appear in Rembrandt, with a report of anything that could not come over.

What you need first

  • A computer running macOS, Windows or Linux with a photo folder you want to edit
  • A terminal for the Linux and self-host install commands
  • A GPU with WebGL 2 support is helpful; the README says older graphics cards are supported at reduced working size
  • Permission to open unsigned builds (System Settings › Privacy & Security › Open Anyway on macOS, More info › Run anyway on Windows)

Steps

  1. Install Rembrandt for your system from the Releases page or the Download table.
  2. Open Rembrandt and choose the Lightroom Classic import option under Bring your photos.
  3. Point the import at your Lightroom Classic catalog and let it run.
  4. Open the import report and note any items the README says cannot come over.
  5. Open a few migrated photos and compare their edits with Lightroom to confirm they look right.

Prompt for your agent

Using the repo thesnarkitecht/rembrandt, run a Lightroom Classic catalog import into Rembrandt for the catalog at <catalog-path>. Report the count of imported edits, keywords and collections, and list every item in the import report that did not come over.

Caveat. The README lists Print, Book, Slideshow, Web and Map modules, face recognition and Adobe's camera profiles as not here yet, so expect some Lightroom work to stay behind.
