Lightroom Plugin

Streamline your verification workflow directly within Adobe Lightroom

Download and install our Lightroom plugin to verify photo authenticity without leaving your editing environment.

What is Lumethic?
Lumethic provides a technical method to prove photographic authenticity through RAW file verification. By comparing your RAW file against the final JPEG, we generate cryptographic proof that links the published image to the original camera capture. This creates a verifiable chain of custody using the C2PA standard.

RAW file verification creates forensic proof of ownership that survives beyond watermark removal

C2PA signatures provide cryptographically-backed evidence of provenance

Shareable verification reports establish trust with clients and publishers

Meet emerging authenticity requirements in editorial, legal, and competitive contexts

Why Verify Your Photos?
The challenge photographers face: proving authenticity when it matters most

The Authenticity Challenge

AI models can be trained on your work without consent or compensation
Advanced AI tools can remove watermarks with increasing precision
Photo contests increasingly require proof of authenticity beyond metadata
Publishers and clients need verifiable evidence in the age of generative AI

The RAW File Verification Approach

RAW files serve as your 'digital negative' - unfeasible to counterfeit
C2PA manifests create tamper-evident records of an image's history
Verification reports provide shareable proof of the RAW-to-JPEG lineage
Direct integration eliminates the need to switch between tools
System Requirements
  • Adobe Lightroom Classic 11.0+ or Lightroom CC 5.0+
  • Windows 10+ or macOS 10.15+
  • Active Lumethic account
  • Valid API key from your Lumethic profile
Key Benefits
  • Seamless integration with your existing Lightroom workflow
  • Automatic RAW file processing and JPEG generation
  • Batch verification of multiple photos at once
  • Protect your copyright with cryptographic proof beyond watermarks
  • C2PA-compliant signatures for industry-standard provenance
  • Build trust with verification reports you can share with clients
Troubleshooting

Plugin not showing up in Lightroom?

Make sure you've extracted the plugin to a permanent location and restarted Lightroom after installation.

Getting API authentication errors?

Verify your API key is correct and that your Lumethic account has sufficient credits for verification.

Upload failing or timing out?

Check your internet connection and ensure the RAW files aren't corrupted. Large files may take longer to process.
