LUF Admin Posted December 4, 2024 Share #1 Posted December 4, 2024 Advertisement (gone after registration) Your admin needs a bit of help: I'm writing a book about „AI & Photography“ (sorry, German only). One chapter will be about labeling images as „non AI“ via the CAI standard C2PA. The Leica M11-P is the first camera which signs their image with C2PA. What I'm looking for is an image sample I can use for this chapter: the image itself how its certificate is shown – as unedited image as well as after edits in photoshop Does one of our members has such an image for me? Shot with Leica M11-P Free of rights of thirds parties C2PA data included Permit to publish in a book (with credits of course) Please contact me via PN!

JBushey Posted May 28 Share #3 Posted May 28 Question - Why are my CC in Leica M 11-P not recognized in Verify? I am working on a research article [In English] on Digital Images, AI-gen Images and Trust. We are currently testing the M 11-P and Content Credentials. I am shooting JPG images right now and I have Content Credentials "sign" turned on in camera, including my name in the Copyright and Produced by info. I shoot an image. I download the image to my MAC computer using Adobe Lightroom. If I drag and drop that original digital image into CC verify: https://contentcredentials.org/verify the result is an "unrecognized" file, with no CR icon. If I scroll down in the verify window, I can see my Produced by information from the camera and the Issuer as Leica AG. I can see Camera and Lens info and capture date. However there is a warning that the Content Credential Issuer couldn't be recognized. The file may not come from where it claims to be. ??? My expectations are that the CC I entered in my camera would make the file recognizable and trusted - earning the file a CR icon. Is anyone else experiencing this result? IF I export the image from Adobe Lightroom with CC option ON and drag & drop that file in verify, then I get a file with CR icon and Issuer as Adobe Inc, but the ingredients include my unidentified prior image from Leica AG. I also noticed that my Produced by info is now coming from the Adobe Lightroom app. 1 Quote Link to post Share on other sites More sharing options...

Tseg Posted May 29 Share #5 Posted May 29 (edited) I use Photomator/Pixelmator in Mac to edit. If I move a DNG or SOOC camera created jpg from Mac Photos to the Content Credentials website the CC function works perfectly. The moment I make any edits on non-content credential certified software, like what I use, the verification website no longer picks anything up. But my information is in the file TIFF. I originally was excited about content credentials because I thought my info would live in my images forever with some type of blockchain-based methodology. The way it looks to me now, if I see my image being improperly used months or years out, I would have to go back to my original DNG/SOOC JPG to prove authentication. Is this a correct understanding?

I also noticed that my Produced by info is now coming from the Adobe Lightroom app. I had a similar observation... but then realized during some camera reset (firmware install?) my Content Credentials info in camera was deleted and set to off. Once I typed my name back into my camera and turned on CC it worked again. Is yours turned on? Welcome, dear visitor!

JBushey Posted June 4 Share #7 Posted June 4 Advertisement (gone after registration) Thanks Tseg. My CC on the Leica are ON and yet I get "unrecognized" when I identify my jpeg out of the camera.

I guess your Leica is counterfeit? /jk I'm not sure why you are getting unrecognized? Also, your listed device does not have the little Leica logo next to it. Odd.

JBushey Posted June 4 Share #9 Posted June 4 (edited) Thanks for your input. I'll keep trying to figure this out. I'll update my firmware to 2.2.3 and see if that solves it. Edited June 4 by JBushey Quote Link to post Share on other sites More sharing options...
