Nikon has temporarily suspended its Nikon Authenticity Service program, which provided Z6III owners with the ability to sign their images with C2PA Content Credentials. In a notification, the company says it “confirmed that an issue has been identified in the Nikon Authenticity Service,” and that “the service has been temporarily suspended while we work diligently to resolve the issue.”
While the company didn’t specify what the issue was, it seems likely it’s related to a discovery made by DPReview forum member Horshack, who got the camera to sign an image it hadn’t exactly taken by using the Multiple Exposure function. Yesterday, Nikon told DPReview it was investigating that issue.
The Z6III’s ability to create these Content Credentials, which theoretically help prove that a photo was authentically taken with a camera and keep a record of edits made to it, was a headline feature of the Z6III’s v2.0 firmware update. However, the company did tell users that it was being released as a beta, so it’s not necessarily surprising that there have been a few bugs.
In its news post, Nikon promises to provide an update “as soon as the corrective measures are complete,” and apologizes for any inconvenience.
Special thanks to Horshack for alerting us to Nikon’s news post.

Our DPREVIEW Tribute:
After nearly 25 years of operation, DPReview closed on 10 April 2023. This difficult decision was part of the annual operating plan review that parent company, Amazon, shared earlier this year.
Over the course of 25 years, DP Review built up a reputation as being one of the most informative places to go for information about that new camera or lens you’re after. DP Review began as an independent reviews site based in the UK in 1998, the brainchild of Philip and Joanna Askey, but it was eventually purchased by Amazon in 2007 and relocated over to Seattle in the USA in 2010.
Cheers DPReview – thanks for the great work and content that guided photographers, videographers and techno junkies the world over!
