C2PA Investigations

This is the blog version of my talk at the IPTC’s online Photo Metadata Conference conference. Its title is the one the conference organizers slapped on my session without asking; I was initially going to object but then I thought of the big guitar riff in Dire Straits’ Private Investigations and snickered. If you want, instead of reading, to watch me present, that’s on YouTube. Here we go.

Hi all, thanks for having me. Today I represent… nobody, officially. I’m not on any of the committees nor am I an employee of any of the providers. But I’m a photographer and software developer and social-media activist and have written a lot about C2PA.
