Prove Your Photos Are Real. Protect Your Work.
In a world of fakes, stand out with undeniable proof of authenticity. Lumethic provides the tools to protect your work, build trust with clients, and increase the value of your photography.
Content Verification
We verify the actual visual content in your JPEG matches your camera's RAW file using multi-factor forensic analysis that detects manipulation while allowing standard edits.
Retroactive Signing
Add secure C2PA signatures to photos you captured months or years ago if you still have the RAW files.
No credit card required • 5 free verifications
What Makes Lumethic Different
Content verification and retroactive signing for professional photographers
Multi-Factor Content Verification
Most verification systems only check metadata, camera model, timestamps, file relationships. These can be easily manipulated or don't detect content changes.
Lumethic verifies the actual visual content:
Physical Plausibility
Validates RAW sensor characteristics to ensure the file exhibits properties consistent with genuine camera output
Structural Similarity
Analyzes image structure and patterns using SSIM algorithms to verify visual content integrity
Statistical Correlation
Examines color spaces, histograms, and pixel relationships across multiple channels
Content-Aware Validation
For portraits, verifies facial similarity to ensure subjects haven't been altered or replaced
These methods work independently and examine different image properties. Passing all of them provides strong computational evidence your JPEG is an authentic derivative of your RAW file.
Read our technical deep dive →Retroactive Archive Protection
Have published photos with preserved RAW files? Verify and sign your existing work, whether captured last month or years ago.
Use cases for retroactive signing:
- •Portfolio pieces and award winners
- •Frequently licensed stock photos
- •Work involved in copyright disputes
- •Photos needed for legal evidence
- •Contest submissions requiring verification
The C2PA signature timestamp shows when verification occurred, not original capture date. Original dates remain in EXIF metadata—we're transparent about timeline.
Why Photographers Choose Content-Verified Provenance
Multi-factor verification and transparent methodology
Detect Manipulation While Allowing Edits
Our verification distinguishes between legitimate RAW processing (exposure, color, cropping) and content manipulation (adding/removing elements). This means you can edit professionally while still proving authenticity.
Standard Lightroom adjustments pass verification. Significant content changes are flagged which is exactly what verification should do.
Retroactive Archive Protection
Verify and sign your existing work if you preserved your RAW files. Add C2PA provenance to photos captured years ago, protecting your archive and establishing ownership of published work.
Particularly valuable for portfolio pieces, award winners, and frequently licensed images.
Documented Content Validation
Having the RAW file is not enough what matters is validation that your JPEG actually shows content from the RAW unaltered. Our verification report provides computational evidence that your JPEG authentically represents your RAW's content evidence that's auditable by third parties.
Contest judges and legal cases increasingly require documented validation that the RAW and final image match, not just RAW file possession.
Multi-Factor Forensic Analysis
Unlike single method detection, our verification uses orthogonal analysis techniques. Each method examines different image properties: structural, statistical, perceptual, and content-aware.
Defeating all methods simultaneously is exponentially harder than bypassing any single check.
Transparent and Auditable Results
Verification reports show methodology, scores, and confidence levels. Anyone can review the evidence and understand how verification was performed, building trust through transparency.
Critical for legal, editorial, and scientific contexts where verification methodology must be defensible.
Add Verification to Your Workflow
Three steps to content-verified, C2PA-signed images
Complete Your Edit and Export
Process your RAW file in Lightroom, Capture One, or your preferred software. Standard adjustments like exposure, color correction, cropping, and spot removal are fully supported. Export your final JPEG or TIFF.
Our verification accounts for legitimate RAW processing while detecting content manipulation.
Upload RAW and Final Image
Upload both files to Lumethic. Our system performs forensic analysis:
- •Validates RAW physical properties (sensor characteristics)
- •Compares structural similarity between RAW and JPEG
- •Analyzes statistical correlations across color spaces
- •Checks content integrity (including facial similarity for portraits)
You'll see detailed results showing which verification methods passed and their confidence scores.
Receive C2PA Signed Image and Verification Report
Your JPEG is returned with a cryptographically signed C2PA manifest embedded, proving the verification took place. You also receive a detailed verification report that includes:
- •Verification methodology and results
- •Cryptographic hashes linking RAW to JPEG
- •Timestamp of verification
- •Shareable URL for third-party review
Share the verified, signed image with clients, submit to contests, publish in editorial contexts, or use in legal proceedings.
Workflow Integration: For photographers using Lightroom, our plugin automates this process during export, making verification a seamless part of your workflow.

Who Uses RAW File Verification
Professional photographers who need documented proof of authenticity
News organizations increasingly require photographers to verify image authenticity. Verification reports provide technical documentation without requiring RAW file submission to third parties.
Major news outlets have implemented mandatory authenticity verification policies following high-profile incidents involving manipulated images.
Major contests require evidence that entries are camera originated. Verification reports provide this documentation while keeping your RAW files secure.
The World Press Photo contest requires contestants to provide RAW files or equivalent proof of authenticity for all entries.
Document authenticity for newsworthy images in real-time. Verification reports provide evidence that images haven't been manipulated, critical for maintaining credibility and meeting editorial standards.
Wire services and news agencies require authenticity documentation for images used in breaking news coverage.
Prove authenticity of wildlife captures for conservation documentation, nature publications, and contests. Verification confirms animals were photographed in natural settings without digital manipulation.
Wildlife photography competitions have strict rules against manipulated images after several high profile disqualifications.
Document authentic action captures for licensing, publication, and editorial use. Verification proves decisive moments were captured in-camera without composite manipulation.
Particularly important for iconic sports moments that may be licensed or disputed.
In a market flooded with AI-generated content, verification helps differentiate authentic camera-captured work. Leading stock platforms now specifically seek verified authentic images.
Enterprise buyers increasingly have policies requiring documented image provenance for commercial use.
Prove that property photos accurately represent the actual property without misleading edits. Verification builds trust with buyers and protects against disputes about photo authenticity.
Particularly important for high-value properties and luxury real estate where authenticity claims matter.
Create documented provenance for collectors and galleries. Verification records support the authenticity of limited edition prints and increase artwork value.
Essential for higher-value works where provenance and authenticity directly impact market value.
Document that images used in peer-reviewed research, academic publication, or scientific documentation are authentic camera captures rather than illustrations or AI-generated content.
Academic journals increasingly require authenticity verification for published imagery.
Pricing for Professional Photographers
Choose based on your typical monthly output
