If your firmware is older than the versions listed above, update it before proceeding. Firmware updates are available free from Nikon's download centre at downloadcenter.nikonimglib.com.
Setup: step by step
Go to the Setup Menu (wrench icon) and scroll to Firmware version. Confirm your camera is running at least the minimum version listed above. If not, download and install the update from Nikon's support site before continuing.
Content Credentials on Nikon cameras are managed through the NX MobileAir companion app (iOS and Android). Download it from the App Store or Google Play. This app handles the initial certificate provisioning and connects your camera to Nikon's C2PA signing infrastructure.
Open NX MobileAir on your phone. On your camera, navigate to:
Follow the on-screen prompts to pair your camera via Bluetooth. Once paired, the app will display your camera model and connection status.
In NX MobileAir, navigate to the Content Credentials section. You'll be asked to create or sign in to a Nikon ID (if you haven't already). Once authenticated, the app will provision a C2PA signing certificate to your camera. This certificate is what cryptographically signs each image.
You can optionally configure what information is included in the credentials - your name, copyright notice, and whether GPS location data is embedded. All identity fields are optional.
Once the certificate is provisioned, enable Content Credentials on the camera itself:
On some models this appears under the Setup Menu rather than Photo Shooting Menu. Look for "Content Credentials" or "Image Authentication" in either location.
Once enabled, a small C2PA icon will appear in the viewfinder and on the rear LCD, confirming that every image you capture will be signed.
Take a test photo. Transfer it to your computer (via card reader, USB, or wireless). Go to contentcredentials.org/verify and upload the file. You should see a valid Content Credential showing the camera model (e.g. "NIKON Z 9"), the capture time, and any optional information you configured.
If the verification shows "No Content Credentials found," check that you enabled the feature on the camera (Step 5), that the firmware is up to date (Step 1), and that you transferred the original file without conversion or re-saving.
What gets recorded
When Content Credentials are enabled, each image's manifest includes the camera manufacturer and model, a device serial number (configurable), the capture timestamp, optional GPS coordinates (if location is enabled on the camera), optional creator name and copyright notice (configured in the app), and a cryptographic hash binding the credentials to the image data.
Performance impact
In our testing, enabling Content Credentials on the Z9 and Z8 has no noticeable impact on continuous shooting speed, buffer depth, or write times. The cryptographic signing operation is extremely fast and runs during the normal card write process. You should not experience any difference in real-world shooting performance.
Editing signed images
When you open a Nikon C2PA-signed image in Adobe Photoshop or Lightroom, the software recognises the existing Content Credential and chains a new manifest to it. Your edits are recorded, and the original capture credential is preserved as an "ingredient." Export with Content Credentials enabled in the export settings to maintain the full provenance chain.
If you edit in software that doesn't support C2PA (Capture One, Affinity Photo, etc.), the original credential will be preserved in the file but no new edit manifest will be added. The capture-level provenance remains intact, but the edit history won't be recorded.
Credentials not appearing in Verify: Ensure you're uploading the original NEF/JPEG file, not a screenshot or re-exported version. Some transfer methods (AirDrop, certain cloud services) can strip metadata.
"Unrecognised signer" warning: This typically means your camera's certificate hasn't been updated to the latest C2PA Trust List. Ensure NX MobileAir is up to date and re-provision the certificate.
Feature not visible in menu: Confirm your firmware meets the minimum version. On some models, the menu item only appears after pairing with NX MobileAir at least once.
