Question 1

What is Lumethic in simple terms?

Accepted Answer

Lumethic verifies that a photo is real and unmodified by comparing the final image to the original camera RAW file, then produces a shareable proof report.

Question 2

How does Lumethic help photographers sell?

Accepted Answer

Verified authenticity builds trust and reduces buyer risk. Link your verification when selling so buyers can confirm the photo is authentic before purchasing.

Question 3

How secure are payments for photo sales?

Accepted Answer

All payments are processed securely through Stripe, one of the world's most trusted payment platforms. We never store your payment information. Stripe handles all transactions with bank-level security, PCI compliance, and fraud protection, ensuring safe and reliable payments for both photographers and buyers.

Question 4

How can buyers use a verification report?

Accepted Answer

Click the link to view a transparent report showing authenticity checks. Use it to evaluate risk and proceed with confidence. Learn more at /verify-photos.

Question 5

Do you store my RAW files?

Accepted Answer

No. RAW files are processed temporarily for analysis and deleted immediately afterwards.

Question 6

What does ‘RAW-linked verification’ mean?

Accepted Answer

It means the final image (e.g., JPEG) is forensically tied to the original camera RAW file. We analyze both to confirm that the JPEG plausibly descends from that RAW without prohibited content alterations, producing a tamper-evident provenance link.

Question 7

How is Lumethic different from EXIF checks or reverse image search?

Accepted Answer

EXIF data is easily altered and reverse image search only finds exact copies. Lumethic performs a much deeper, RAW-to-final comparison using multiple forensic signals, resulting in a clearer, more trustworthy report.

Question 8

Can Lumethic detect AI-generated images?

Accepted Answer

Our primary focus is on verifying authenticity by linking an image to a real camera RAW file. If no such RAW file exists for an image, it cannot be verified through our system, which is a strong signal against its authenticity. This is a more robust method than relying on AI detectors, which can be unreliable.

Question 9

Do edited photos pass verification?

Accepted Answer

Yes. Standard adjustments like color correction, cropping, and tonal changes are expected and will pass. The goal is to detect significant content manipulation, such as adding or removing key elements from the scene.

Question 10

Which file types are supported?

Accepted Answer

We support a wide range of camera RAW formats (like .CR2, .NEF, .ARW, .DNG) and common final image formats like JPEG and TIFF. We are continuously expanding our support.

Question 11

Why does Lumethic only accept RAW files as source?

Accepted Answer

RAW files provide the strongest evidence that an image was captured by a real camera. They contain unprocessed sensor data with physical characteristics (sensor noise patterns, file size vs. resolution ratios, bit depth consistency) that are extremely difficult for AI to forge convincingly. While not cryptographic proof, RAW files offer strong probabilistic evidence of camera origin. In the future, we will also support camera signed JPEGs that provide cryptographic proof once manufacturers implement signing standards like C2PA Content Credentials.

Question 12

Will Lumethic support camera-signed JPEGs in the future?

Accepted Answer

Yes. As soon as camera manufacturers and smartphone makers adopt cryptographic signing standards (like C2PA Content Credentials), Lumethic will support these cryptographically signed JPEGs as source files. As of October 2025, only a few Leica cameras (M11-P, M11-D, SL3-S) implement camera-native C2PA signing. No other camera manufacturers or smartphone brands have adopted this technology yet.

Question 13

Do smartphones support cryptographic photo signatures?

Accepted Answer

No. As of October 2025, no smartphones including iPhones and Android devices from Google, Samsung, or any other manufacturer implement cryptographic photo signatures or C2PA Content Credentials. Lumethic will adopt smartphone-signed photos as soon as manufacturers add this capability to their devices.

Question 14

How long does verification take?

Accepted Answer

Most verifications complete within a few minutes. The time can vary depending on the size of your files and current server load.

Question 15

Are reports public or private?

Accepted Answer

You have full control over the visibility of your reports. You can keep them private, share them via a direct link, or embed them publicly.

Question 16

Can I remove a report later?

Accepted Answer

Yes, you can delete a verification report at any time. This will disable the public link, preventing future access.

Question 17

Is Lumethic GDPR-compliant?

Accepted Answer

Yes. We are GDPR-compliant by design. We practice data minimization, process RAW files transiently, and honor user rights for data access, export, and deletion.

Question 18

Do you have an API?

Accepted Answer

Yes, we have a REST API that allows for automated verification workflows. You can find the documentation in the user dashboard.

Question 19

How is pricing structured?

Accepted Answer

We offer a free tier to get you started, along with paid plans that provide more verifications and features to suit professional and business needs.

Question 20

Who is Lumethic for?

Accepted Answer

Lumethic is for professional photographers, photo agencies, journalists, and any organization that needs to ensure the integrity of their visual content. It helps creators prove their work is real and helps buyers trust what they see.

Question 21

Does verification prove copyright ownership?

Accepted Answer

While a RAW-linked verification provides strong evidence of authorship and the image's history, it is not a legal registration of copyright. We recommend using it alongside traditional copyright registration as part of a complete protection strategy.

Question 22

Can I verify video or audio?

Accepted Answer

Currently, we are focused exclusively on still images. Support for other media types like video is something we are exploring for the future.

Question 23

How do I get started today?

Accepted Answer

Simply create a free account, upload a RAW file and its corresponding final image, and generate your first verification report. You can then share the link with clients or on your portfolio.

Question 24

Does Lumethic run a public marketplace?

Accepted Answer

Not at this time. Lumethic focuses on verification and private sales via secure links shared by photographers. There is no public browseable catalog.

Question 25

Will you ever store or share my RAW files?

Accepted Answer

No. RAW files are processed once for forensic analysis and immediately deleted. Only the verification report and your final deliverables are shared.

Question 26

Why do RAW files prove ownership?

Accepted Answer

Only the photographer who captured the image has access to the camera's RAW file. If someone steals your JPEG, they cannot create a verification because they don't have the RAW. This makes Lumethic verification a strong indicator of copyright ownership.

Question 27

How transparent is your verification process?

Accepted Answer

Our reports provide clear, verifiable proof of an image's origin and authenticity. We believe in transparency and making verification accessible to everyone. All verification steps and results are clearly documented in the report.

Question 28

Can a stolen JPEG be verified by someone else?

Accepted Answer

No. Only the original photographer with access to the camera RAW can create a valid verification, which helps deter theft and supports ownership claims.
